Crow case method: 50 questions

7 a.m. in June, the morning after rain. Yesterday you rescued a juvenile large-billed crow that could not move in a park, contacted the prefectural wildlife office, and are holding it temporarily. The bedding in the cardboard box is damp, and this morning the bird is breathing with its mouth open and its whole body heaving, with a wheezing sound coming from its chest. Its feathers are fluffed and its eyes are half closed.

Which is the most appropriate first action?

1. Move it from the damp box to a dark box with dry bedding, keep it warm, and take it to a hospital that sees wild birds the same day
2. Put a humidifier nearby to ease breathing, mist the body with a spray bottle and watch
3. Bring food to its beak to perk it up and push it in by hand until it eats
4. Leave the box lid open so it is not frightened and keep talking to it from nearby

AnswerA. Move it from the damp box to a dark box with dry bedding, keep it warm, and take it to a hospital that sees wild birds the same day

ExplanationStress right after rescue and damp conditions are the classic triggers for aspergillosis (a fungal infection), and open-mouth breathing with respiratory noise are its key signs. Moving the bird away from the damp bedding, resting and warming it in a dark, well-ventilated box, and seeing a vet the same day is the response the manual calls for. Humidifying or misting helps mold grow and makes things worse. Force-feeding a weak bird risks aspiration and choking; feeding is done gradually under veterinary guidance. Leaving the lid open and talking constantly is a severe stressor for a wary crow and worsens its breathing. Treat labored open-mouth breathing as a "call now" case.

IssuesThe rescued bird was already weak, and leaving the bedding damp created an environment prone to fungal infection. The problems were failing to check that the bedding was dry and ventilated at rescue, and having no habit of observing the bird's breathing rate.

ImprovementChange newspaper or pet sheets daily and replace them immediately if damp. Keep the rescue box in a dark, quiet place with ventilation. Learn the resting breathing rate (about 20–30 per minute) as a benchmark, and decide in advance that open-mouth breathing or respiratory noise means a same-day vet visit. Find a hospital that sees wild birds ahead of time.

6 p.m. in July. You rescued a weak carrion crow that had recently fledged, have contacted the wildlife office, and the vet appointment is tomorrow morning. When touched, its keel bone is as sharp as a blade; it is fluffed up, cannot stand, and has its eyes closed. A family member says "it must be starving," has prepared a lot of chicken breast and bread, and wants to feed it all right now.

Which is the most appropriate response tonight?

1. Hunger is the cause, so let it eat as much chicken and bread as it wants to rebuild its strength
2. Pour sports drink into its mouth with a syringe to fix the dehydration all at once
3. Put it in a dark box at around 30°C, give only small amounts of fluid without forcing food, and see the vet first thing in the morning
4. Put in a bathing dish so it can clean itself and watch it in a bright room

AnswerC. Put it in a dark box at around 30°C, give only small amounts of fluid without forcing food, and see the vet first thing in the morning

ExplanationSuddenly feeding a bird that has been malnourished for a long time can cause a sudden collapse because its body cannot handle the metabolic load. The manual says: "Do not feed large amounts right after rescue. Warm first, give small amounts of fluid, then feed gradually under veterinary guidance." A weak bird cannot maintain its body temperature, so warming to around 30°C is the top priority. Syringing liquid into the mouth carries a high aspiration risk, and bread is low in nutrition and must not be overfed. Bathing robs body heat, and a bright room adds stress. A bird that is limp and cannot get up is a "call now" case, so if an after-hours hospital is available, consider going tonight.

IssuesThe biggest risk was the well-meaning assumption that "if it is thin, just feed it." The family had not shared the order of warmth and fluids first for a weak bird, and had not identified a hospital that could be consulted at night.

ImprovementWrite the rescue steps on paper for the family: warm, then dark and quiet rest, then small amounts of fluid, then feeding under veterinary guidance. Have disposable warmers or a hot-water bottle wrapped in a towel ready to maintain around 30°C. Note the contacts for a hospital that sees wild birds and an emergency (after-hours) animal hospital, and contact them the day of rescue.

8 a.m. in October. A large-billed crow (5 years old) you have kept under permit for two years. Since yesterday it has responded sluggishly to food; this morning there are several bright green watery droppings on the newspaper, and its right wing looks lower than the left. It staggered when stepping down from the perch. A few days ago you put a fishing sinker you picked up on a riverbank into the aviary as a toy.

Which is the most appropriate first action?

1. Treat it as seasonal malaise, mix vitamins into the food and watch for a week
2. Remove the sinker, provide food and water, keep warm, and see a vet the same day to request an X-ray for metal foreign bodies
3. Make it drink large amounts of water to flush the poison and wait until the droppings return to normal
4. The wing is drooping, so judge it a fracture, tape the wing to the body and see a vet tomorrow

AnswerB. Remove the sinker, provide food and water, keep warm, and see a vet the same day to request an X-ray for metal foreign bodies

ExplanationThe combination of green droppings, a drooping wing, unsteadiness and loss of appetite is the classic picture of lead poisoning, and it most likely swallowed the fishing sinker. Lead poisoning does not resolve on its own and leads to seizures and death if left, so you must see a vet the same day and have an X-ray check for metal foreign bodies. Watching with vitamins wastes time while lead keeps being absorbed. Forcing water does not remove lead and risks aspiration. Assuming the drooping wing is a fracture and taping it as an amateur is pointless if it is neurological, and damages feathers and skin.

IssuesThe direct cause was giving fishing tackle of unknown origin as a "shiny toy." There was insufficient knowledge that crows swallow shiny objects and metal and that lead is especially dangerous. There was no procedure for checking the safety of items put in the aviary.

ImprovementLimit toys in the aviary to items free of lead, small metal and rubber, and never use found objects. Rotate safe toys such as food-hiding puzzles, pine cones and twigs. Observe the color and amount of droppings daily, and decide in advance that green droppings, unsteadiness or a drooping wing means a same-day vet visit.

9 p.m. in late August. A permitted carrion crow (3 years old) kept in a garden aviary. Since evening its head has tilted to the right, it cannot get onto the perch, and it keeps staggering around the floor in the same direction. Mosquitoes have been numerous for several days and the aviary netting has a tear. You heard a dead crow was found on a road in the neighborhood a few days ago.

Which is the most appropriate first action?

1. Put it in a low box, dark and quiet, so it cannot hit the walls, and immediately contact an after-hours hospital and the prefectural wildlife office
2. Assume heatstroke, put it in a cold bath to cool it down and then watch
3. Assume stress, offer its favorite boiled egg to cheer it up and observe until next week
4. Try to correct the head tilt by supporting the head with your hand and holding it straight

AnswerA. Put it in a low box, dark and quiet, so it cannot hit the walls, and immediately contact an after-hours hospital and the prefectural wildlife office

ExplanationNeurological signs such as head tilt, circling and seizures occur with mosquito-borne West Nile fever and avian malaria, and also with lead poisoning. The torn netting, many mosquitoes and a wild bird death nearby strongly suggest infectious disease, and the manual says "seek care immediately and report to the prefectural government." First rest the bird in a low, dark box so it does not crash into the walls; neurological signs are a "call now" case, so contact them even at night. A cold bath robs body heat and accelerates weakness. While watching with boiled egg, the condition can progress to sudden death. Holding the head is a major stressor and a cause of injury, and does nothing.

IssuesThe biggest risk factor was leaving the aviary netting torn and letting mosquitoes in. Despite hearing about a wild bird death nearby, the owner did not connect it to the possibility of infectious disease or take precautions. Awareness that neurological signs are an emergency was also weak.

ImprovementFit fine mosquito netting to the aviary and repair any tear the day it is found. If wild birds die or behave abnormally nearby, ask the wildlife office for information and step up observation in the aviary. Agree as a family that head tilt, seizures or severe unsteadiness means contacting a vet immediately even at night, and keep an after-hours hospital on file.

10 a.m. in September. Yesterday you rescued a crow dragging one wing by the roadside, contacted the wildlife office, and the vet appointment is tomorrow. This morning, when you tried to check the bird in the cardboard box with bare hands, many tiny insects were moving at the base of its feathers and the bird was scratching constantly. You also felt a crawling itch on your own arm.

Which is the most appropriate first action?

1. Spray a dog flea spray generously over all the feathers to kill the insects
2. Shower-wash the bird in the bathroom to remove the insects and dry it with a hair dryer
3. It is natural, so do not worry and keep caring for it as is
4. From now on handle it with gloves, seal and dispose of the bedding, wash your arms, and ask the vet for deworming and a fecal exam at the scheduled appointment

AnswerD. From now on handle it with gloves, seal and dispose of the bedding, wash your arms, and ask the vet for deworming and a fecal exam at the scheduled appointment

ExplanationRescued wild birds almost always carry external and internal parasites, and mites can transfer to people and cause dermatitis. The manual says "handle with gloves; have the vet run a fecal exam and deworm" and "seal bedding in a bag before disposal." Dog insecticides have no confirmed safety in birds and would be an overdose for a crow's body weight, risking poisoning. Shower-washing robs a weak, injured bird of body heat and worsens the wing injury. Left untreated, anemia and dermatitis progress and infection spreads to people and other animals in the home. The vet visit can wait until tomorrow as scheduled, but stop bare-hand handling from today.

IssuesThe problem was touching the rescued bird with bare hands. The owner lacked the knowledge that wild birds should be handled on the assumption they carry parasites and pathogens. Leaving used bedding lying around also risks spreading mites through the house.

ImprovementWear thick gloves when caring for a rescued bird and wash hands with soap afterward. Change bedding daily and seal it in a bag for disposal. Do not share equipment with other birds, and always get deworming and a fecal exam at the first vet visit. If the itch on your arm persists, see a dermatologist yourself.

A November afternoon. A large-billed crow (7 years old) kept under permit for three years. For the past week it has often stood on its left leg with the right raised; today on close inspection the right sole is red and swollen with a scab. The aviary perches are only identical round commercial dowels of the same thickness, and the floor is bare concrete. It has been exercising less lately and has gained some weight.

Which is the most appropriate first action?

1. Apply human blister ointment, bandage it and watch for a month
2. Switch to natural-wood perches of different thicknesses, soften the floor, and see a vet within a few days for treatment
3. Remove the perches so it lives on the floor and rests its feet
4. The pain is all in its head, so distract it with more play

AnswerB. Switch to natural-wood perches of different thicknesses, soften the floor, and see a vet within a few days for treatment

ExplanationPerches of a single thickness, a hard floor and obesity are the three main causes of bumblefoot (inflammation of the sole), and redness, swelling, scabs and one-legged standing are its classic signs. As it progresses the infection reaches the bone, so improve the environment and see a vet within a few days for treatment. Human ointments have unknown safety in birds and can cause poisoning when ingested during preening. Removing the perches and leaving the bird on hard concrete increases the load on the soles. Dismissing the pain as imaginary is wrong; the lesion will not heal on its own. It is not an emergency, but not something to leave either.

IssuesWith one perch thickness and a hard floor, the environment put chronic strain on the soles. Lack of exercise and obesity accelerated it. One-legged standing continued for a week, but with no habit of checking the soles daily, detection was delayed.

ImprovementInstall several natural-wood perches of different thicknesses at varying heights and soften part of the floor with soil or dead leaves. Add the soles, beak and eyes to the daily checklist. Increase activity with food-hiding puzzles and weigh the bird regularly to prevent obesity.

A February morning. A permitted carrion crow (12 years old). It is usually the first to approach at the morning feeding, but today it does not come out from the back of its hide box and does not stretch its neck toward the food. On closer inspection it is fluffed up into a ball with its eyes closed, and yesterday's droppings were scant. The water in the aviary is frozen and the outside temperature is below freezing.

Which is the most appropriate first action?

1. Blame the cold, put a heater inside the aviary to warm it up fast, and leave for work
2. Accept that it is old and may be dying, and watch quietly
3. It should eat if the food is changed, so put out extra raw meat and wait for a response
4. Move it to a dark box at around 30°C, provide water, and see a vet today

AnswerD. Move it to a dark box at around 30°C, provide water, and see a vet today

ExplanationFluffed up and motionless, eyes closed, slow response to food and reduced droppings are key signs of deterioration on the checklist, and in an elderly bird drained by cold they worsen rapidly. Warm it in a dark box at around 30°C; not eating is a "same day" vet case. Putting a heater in the aviary and leaving it unattended risks fire and overheating, and a sudden temperature jump is itself stressful. Assuming old age misses a treatable illness. Excess raw meat is not recommended, and it is pointless unless the reason it is not eating is addressed.

IssuesAn environment where water froze below zero was left as is, and winter windbreaks and insulation of the hiding place were inadequate. Awareness that elderly birds tolerate cold poorly was weak, and the previous day's sign of reduced droppings was missed.

ImprovementIn winter fit a windbreak to the aviary, put insulation in the hiding place, and change water morning and evening so it does not freeze. On days below the 5–28°C range, have an indoor box ready for shelter. Record the amount and color of droppings and response to food daily, and see a vet early if an elderly bird changes.

A weekend in mid-May. A young large-billed crow rescued three weeks ago with a wing injury, now kept under permit. The wing is healing, but over the past week its weight has dropped from 650 g to 540 g, it sits fluffed up and motionless, and sometimes breathes with its mouth open. Its food is omnivorous-bird food, but you noticed a damp, clumped section at the bottom of the bag.

Which is the most appropriate first action?

1. Replace the food with fresh, keep the bird warm in a dark, well-ventilated box, and see a vet the same day for a respiratory exam
2. To regain weight, mix oil and butter into the food to make it high-calorie
3. Damp food can be used once dried, so sun-dry it before feeding
4. The wing has healed, so prepare for release and return it to the wild

AnswerA. Replace the food with fresh, keep the bird warm in a dark, well-ventilated box, and see a vet the same day for a respiratory exam

ExplanationDamp, moldy food is a major source of aspergillosis, and weight loss, fluffed feathers and open-mouth breathing are its typical signs. Discard the food that caused it, warm the bird in a dry, dark, well-ventilated box, and see a vet the same day for a respiratory exam. Mixing in oil or butter burdens digestion and does nothing about the mold that is the root cause. Drying damp food leaves mold spores and toxins, so it must not be used. Releasing a bird that has lost nearly 20% of its weight and is struggling to breathe amounts to killing it; release decisions follow the permit conditions and are made in consultation with the vet and the wildlife office.

IssuesThe cause was not checking how the food was stored and continuing to feed damp, clumped food. The weight loss went unnoticed for a week because daily weighing and observation were not habits, and awareness that rescued birds have fragile respiratory systems was lacking.

ImprovementBuy food in small bags, store in sealed containers, use up quickly after opening, and discard anything damp without hesitation. Weigh and record at least twice a week. Change the bedding daily and ensure ventilation. Decide that open-mouth breathing or fluffed feathers means a same-day vet visit, and know a hospital that sees wild birds.

An April morning. An adult carrion crow rescued 10 days ago and kept with the wildlife office's permission. It has not yet been seen by a vet. For the past few days watery droppings have spread across the newspaper, its feathers are dull, and it is thin enough that the keel bone can be felt. It has an appetite but does not gain weight. A family member suggests "giving it a little of our intestinal medicine."

Which is the most appropriate first action?

1. Give a small amount of human intestinal medicine and watch for a few weeks until the droppings firm up
2. Give plenty of raw rice or dry bread as an anti-diarrheal
3. Photograph the droppings, see a vet within a few days for a fecal exam and deworming, and handle with gloves until then
4. Water worsens diarrhea, so remove the drinking water and dry it out

AnswerC. Photograph the droppings, see a vet within a few days for a fecal exam and deworming, and handle with gloves until then

ExplanationRescued wild birds are nearly always parasitized, and diarrhea combined with weight loss is the classic picture of internal parasites. Even with an appetite the bird is robbed of nutrition, so it needs a vet visit within a few days for a fecal exam and deworming. A photo of the droppings helps diagnosis. Human intestinal medicine has unknown efficacy and safety in birds and risks overdose for the body weight. Raw rice and bread are low in nutrition and do not treat the cause. Dehydration advances during diarrhea, so removing water is the most dangerous mistake. The bird can also be a source of Salmonella for people, so use gloves and wash hands thoroughly.

IssuesTen days after rescue the bird had still not had an initial vet exam, delaying parasite checks and deworming. The idea of repurposing human medicine for a bird is also dangerous. Awareness of gloves and hand-washing during care was weak, underestimating the zoonosis risk.

ImprovementAlongside contacting the wildlife office, get a rescued bird a health check, fecal exam and deworming at a hospital that sees wild birds as soon as possible. Never give human medicine. Photograph the droppings daily and show changes at the vet visit. Wear gloves for care, wash hands with soap afterward, and do not wash equipment in the kitchen.

5 p.m. in September. A permitted large-billed crow (4 years old) suddenly fell from its perch and had a seizure on the floor, flapping its wings with its whole body rigid. It stopped after about 30 seconds, but it is limp and cannot stand. For a few days its droppings have been greenish, and last week it scattered the contents of an old fishing tackle box left in the aviary.

Which is the most appropriate first action?

1. Keep filming the seizure for the record and watch for the next one
2. Tap its cheek lightly and splash water in its mouth to bring it round
3. Put it in a low box, dark and quiet, and go to the vet immediately with photos of the tackle box and the droppings
4. It is just tired, so put it back on the aviary perch to rest

AnswerC. Put it in a low box, dark and quiet, and go to the vet immediately with photos of the tackle box and the droppings

ExplanationA seizure is one of the most serious signs and a "call now" case, and the green droppings plus contact with fishing tackle strongly suggest lead poisoning. To prevent secondary injury, put the bird in a low box where it cannot hit the walls, keep it dark and quiet, and go to the vet immediately with photos of what it may have swallowed and of the droppings. Filming while waiting for another seizure wastes time and loses the chance for treatment. Tapping the cheek or splashing water is pointless and can trigger aspiration or another seizure. Putting it back on the perch leads to another fall with fractures or head injury. Lead poisoning does not resolve on its own and needs specialist treatment.

IssuesThe root cause was bringing a tackle box, a trove of lead and fishing line, into the aviary. The owner underestimated the crow's habit of swallowing shiny objects and metal and did not check the contents when the bird scattered them. Had the bird been seen when the green droppings appeared, the seizure might have been prevented.

ImprovementNever bring lead items, fishing tackle, small metal objects or rubber into the enclosure. Inspect small items in the aviary daily and check nothing is missing. Decide that green droppings, unsteadiness or a drooping wing means a same-day vet visit. Keep a low cardboard transport box and the hospital and wildlife office contacts where they can be grabbed at once.

A March afternoon. A permitted large-billed crow (6 years old). Since this morning it has repeatedly picked up food and dropped it, and is eating less. Up close, the tip of the upper beak is chipped and slightly bloody. For several days you had seen it striking its beak against the wire mesh again and again, but thought it was play.

Which is the most appropriate first action?

1. File the chipped part smooth and reinforce it with superglue
2. Chop food small and soft to make it easier to eat, see a vet the same day or within a few days, and discuss the cause of the striking against the mesh
3. It will grow back on its own, so give more hard food and wait for it to wear down
4. Remove food and water to rest the mouth until the pain subsides

AnswerB. Chop food small and soft to make it easier to eat, see a vet the same day or within a few days, and discuss the cause of the striking against the mesh

ExplanationA chipped beak hinders feeding and can lead to bleeding, infection and involvement of the bone, so help the bird eat with small, soft food while seeing a vet the same day or within a few days for treatment and to discuss the cause. Filing or gluing as an amateur damages tissue that carries nerves and blood vessels, and glue components risk poisoning. Hard food will split the chipped part further. Removing food and water causes weakness and dehydration. Striking the mesh may be boredom, stress or territorial behavior rising in the breeding season, so the environment needs reviewing.

IssuesThe owner dismissed the beak-striking as play and did not take it as a sign of stress or boredom. With no habit of checking the beak daily, detection was delayed. Knowledge that behavior changes during the breeding season (March–July) was also lacking.

ImprovementCheck beak overgrowth or chips, the soles and the eyes in the daily inspection. Provide a rotating daily supply of mentally engaging play such as food-hiding puzzles and twigs, and set aside time for interaction. Territorial drive rises in the breeding season, so add screening to block the view of wild crows outside. Inspect the mesh for damage and protrusions at the same time.

2 p.m. in mid-August. A carrion crow (18 years old) kept under permit for many years. The aviary is in direct sunlight and the bathing dish was empty. Since morning it has been in its hide box with eyes closed, responding sluggishly when called, with its wings held slightly away from the body and hanging limp. It moves slightly when you try to touch it but cannot stand up.

Which is the most appropriate first action?

1. Move it to a dark box in a cool room, provide water, and go to the vet immediately while taking care not to overcool it
2. Immerse the body in ice water to bring the temperature down fast, then return it to the aviary
3. It is just age, so point a fan at the aviary and watch
4. It is short of fluids, so syringe a large amount of water into the back of its mouth

AnswerA. Move it to a dark box in a cool room, provide water, and go to the vet immediately while taking care not to overcool it

ExplanationIn direct sun with no water, a bird that holds its wings away, lies limp and cannot stand is severely weakened, including possible heatstroke; "limp and unable to get up" is a "call now" case. Move it to a dark box in a cool room, provide water, avoid rapid cooling, and go to the vet immediately. Immersion in ice water risks shock from a sudden temperature drop and loss of thermoregulation from wet feathers. Blaming age and leaving it with a fan makes it worse. Syringing large amounts of water carries a high risk of aspiration and choking. The suitable temperature range is 5–28°C; in summer, shade, bathing and ventilation are essential.

IssuesThe cause was a failure of environmental management: no shade from direct midsummer sun and an empty bathing dish. Awareness that elderly birds tolerate heat poorly was weak, and the morning's changes were noticed late.

ImprovementIn summer create shade with shade cloth or a roof, and check and change bathing and drinking water morning and evening. Put a thermometer in the aviary and move the bird to a cool indoor spot on days above 28°C. Increase morning and evening observation of elderly birds and see a vet early if movement or responsiveness declines.

8 a.m. in November, at an intersection on the way to work. A large-billed crow that appears to have been hit by a car is on the sidewalk dragging one wing on the ground, trying to fly and tumbling. The base of the wing is bent unnaturally and there is blood on the feathers. Bystanders say "poor thing, let's take it home and keep it" and are about to grab it with bare hands.

Which is the most appropriate first action?

1. Pick it up with bare hands, take it home, splint the wing and start keeping it
2. First contact the prefectural wildlife office; following their instructions, wrap the wing against the body in a thick towel, put it in a dark box, and see a vet the same day
3. Wild animals should not be touched, so leave it on the road and walk away
4. Flying practice will heal it, so spread its wings and toss it into the air

AnswerB. First contact the prefectural wildlife office; following their instructions, wrap the wing against the body in a thick towel, put it in a dark box, and see a vet the same day

ExplanationWild crows are covered by the Wildlife Protection and Hunting Management Act, and capturing or keeping them without a permit is prohibited. The rule is to contact the prefectural wildlife office before touching an injured bird and rescue it on their instructions. A wing fracture worsens the more the bird tries to fly, so wrap the wing against the body in a thick towel, rest it in a dark box, and take it to a hospital that sees wild birds the same day. Bare-hand capture risks bites, scratches, parasites and infection, and amateur splinting damages bone and nerves. Left on the road it will be run over again. Tossing it up worsens the fracture and is abuse.

IssuesThis is a classic case of good intentions ("poor thing, let's keep it") leading to a legal violation and a worse outcome for the bird. The bystanders did not know that wild birds cannot be kept without a permit or that the office must be contacted before touching, and were unaware of the dangers of bare-hand handling.

ImprovementSave the prefectural wildlife office number in your phone. When you find an injured wild bird, always "contact before touching," and keep a thick towel, leather gloves and a cardboard box with air holes in the car. Know a hospital that sees wild birds in advance.

4 p.m. in May, on a riverbank. A carrion crow is struggling in the grass; up close, fishing line is wrapped many times around both legs, and on one leg it has cut deep, leaving the leg swollen and discolored. You contacted the wildlife office and were told you may rescue it. You have leather gloves, a towel and small scissors.

Which is the most appropriate first action?

1. Grab the line and yank it out, untangle everything and release the bird on the spot
2. Pull the leg until the line snaps and wait for it to come free on its own
3. Cover the head with a towel to calm it, cut only the loose outer line, and leave the embedded part alone and see a vet the same day
4. Burn through the line with a lighter to remove it

AnswerC. Cover the head with a towel to calm it, cut only the loose outer line, and leave the embedded part alone and see a vet the same day

ExplanationCovering the head with a towel to block its vision calms the bird and prevents secondary injury from struggling and bites to people. Loose surface line may be cut with scissors, but a deeply embedded section with swelling and discoloration suggests impaired blood flow or bone damage, and pulling it out as an amateur tears the tissue further and causes bleeding. The manual says "if it has cut into the flesh, do not force it; see a vet," and a same-day visit is needed. Pulling the line to free it can lead to amputation. Burning with a lighter causes burns and risks setting the feathers alight. Necrosis and infection must be assessed after removal, so always have a vet examine it.

IssuesFishing line entanglement cuts off blood flow over time and leads to necrosis. Thinking "untangle it all and release it" on the spot overlooks deep damage and lets the bird die. Not knowing the basics of restraint (cover the head, block vision) injures both the bird and the person.

ImprovementKeep leather gloves, a thick towel, blunt-tipped scissors and a cardboard box in the car when out. Always check legs and wings for entanglement at rescue; if line has cut in, do not cut it and see a vet instead. Keep string and net-like items out of the aviary. Note the contacts for the wildlife office and a hospital that sees wild birds.

A June morning. A young large-billed crow in temporary care under permit was in a makeshift aviary in the garden when a stray cat got in through a gap in the mesh and attacked it. You drove the cat off, but there are two small puncture-like wounds at the base of the wing with slight bleeding. The crow is running around, and the wounds are small, so it looks fine.

Which is the most appropriate first action?

1. The wounds are small and the bird is lively, so apply antiseptic and watch
2. Squeeze the wounds to expel the cat's saliva, rinse well under running water and leave it
3. Let it fly freely in the aviary until the bleeding stops and check on it once it has calmed down
4. Press with gauze to stop the bleeding and see a vet the same day even though the wounds are small

AnswerD. Press with gauze to stop the bleeding and see a vet the same day even though the wounds are small

ExplanationWith a cat bite, even a small wound injects oral bacteria deep into the tissue, and in birds this causes fatal sepsis within days. The manual says "even small wounds carry a high infection risk, so see a vet immediately." First press the bleeding with gauze, rest the bird in a dark box, and see a vet the same day. Antiseptic alone does not reach deep bacteria, and squeezing the wound damages tissue. Letting it fly in the aviary increases bleeding and it may crash into the mesh in fear and sustain new injuries. After a cat attack antibiotics are needed even if the bird looks well; waiting and watching is the most dangerous choice.

IssuesThe makeshift aviary had coarse mesh, a structural problem that let the cat in. The principle of complete separation of rescued birds from other animals was not followed. The feeling that "a small wound is fine" misjudges how serious bites are in birds.

ImprovementBuild the aviary with a roof and fine mesh and inspect for gaps daily. Place it where dogs, cats, other pets and wild animals cannot approach. Decide that any bite means a same-day vet visit regardless of wound size, and keep gauze for pressure and a transport box on hand. Post the contact for a hospital that sees wild birds near the aviary.

An April evening. A permitted large-billed crow (2 years old) got excited by wild crows calling and crashed into the aviary mesh. Afterward a newly growing wing feather (a blood-filled shaft) broke and is dripping blood from the base. A pool of blood is spreading on the newspaper on the floor, and the crow keeps fussing at the feather.

Which is the most appropriate first action?

1. Cover the head with a towel to restrain it, press the base with clean gauze for 5 minutes or more, and if it does not stop, go to the vet while maintaining pressure
2. Pull the broken feather out at the base with pliers to stop the bleeding
3. Sprinkle flour on it to help clotting and return it to the aviary to watch
4. Apply human wound ointment as a styptic and wrap a tight bandage around the whole wing

AnswerA. Cover the head with a towel to restrain it, press the base with clean gauze for 5 minutes or more, and if it does not stop, go to the vet while maintaining pressure

ExplanationA growing feather shaft contains blood vessels and keeps bleeding when broken. A crow has little blood for its body weight, so unchecked bleeding is life-threatening. The manual says "bleeding feather shaft: do not pull it out; apply pressure and see a vet": press with clean gauze for 5 minutes or more, and if it does not stop, go to the vet while maintaining pressure. Pulling with pliers tears the follicle wide open, increases bleeding and damages the skin. Flour is a source of infection with uncertain styptic effect, and back in the aviary the bird will move and bleed again. Human ointment has unknown safety in birds, and a tight wrap around the whole wing restricts breathing.

IssuesThe bird was kept where wild crows were visible, and the risk of excitement and collisions in the breeding season was not anticipated. The aviary mesh had nothing to soften impacts, and knowledge that feather shafts are vulnerable during the molt was lacking.

ImprovementAdd screening outside the aviary so wild crows are not directly visible. Line the inside of the mesh with fine netting to cushion impacts. Keep clean gauze and leather gloves near the aviary. Decide that bleeding means 5+ minutes of pressure and an immediate vet visit if it does not stop, and know an after-hours hospital.

A September morning, cleaning the aviary. A permitted large-billed crow (5 years old) came to your feet, and when you tried to pick it up bare-handed it bit your index finger hard and will not release. The pain makes you want to flail your hand, and the crow is flapping its wings and lunging toward your face.

Which is the most appropriate first action?

1. It hurts, so yank your hand free and fling the bird to the floor
2. Pry the beak open with both hands and hit the bird's head to make it let go
3. Stop moving and protect your eyes, cover its head with a towel to block its vision, and when the grip relaxes hold the base of the beak and release
4. Shout at the bird to frighten it and wait for it to let go

AnswerC. Stop moving and protect your eyes, cover its head with a towel to block its vision, and when the grip relaxes hold the base of the beak and release

ExplanationPulling away when bitten lets the sharp beak tear the skin and deepens the wound. The manual's steps are: stop moving and protect your eyes, cover the head with a towel to block its vision, hold the base of the beak and release when the grip relaxes, then return it to the aviary and stay away until it calms down. Crows go for the eyes, so keeping your face away and protecting your eyes matters most. Prying or hitting damages the bird's beak and head, and it will remember you with fear, permanently damaging the relationship. Flinging it off causes wing or leg fractures. Shouting only heightens excitement. After release, rinse the wound under running water, disinfect, and go to a hospital (for people) for deep wounds.

IssuesThe basic error was trying to pick the bird up bare-handed without leather gloves. Crows are strong and recognize and remember individual people, so rough handling destroys trust. The principle of two-person restraint was ignored, and handling it alone while cleaning was also a problem.

ImprovementWear thick leather gloves and safety glasses when entering the aviary, and handle the bird with two people. Always bring a towel in and share the bite procedure with the whole family. Design the aviary so cleaning can be done with the bird in a separate section. After a bite, rinse under running water and see a hospital (for people) promptly for deep or eye wounds.

A May morning. Several wild large-billed crows in breeding season gathered on the roof of the aviary of a permitted carrion crow (3 years old) and attacked it through the mesh. After you drove them off, the kept bird has scratches on its head and the area around one eye is swollen and discharging a tear-like fluid. It can walk but keeps shaking its head.

Which is the most appropriate first action?

1. The wounds are shallow, so watch in the aviary and see a vet next week if the swelling does not go down
2. Put human eye drops around the eye and cool it until the swelling subsides
3. Rest it in a dark box and see a vet the same day, because an untreated eye injury risks blindness
4. Put food outside so the wild crows are not drawn in and let them make friends

AnswerC. Rest it in a dark box and see a vet the same day, because an untreated eye injury risks blindness

ExplanationHead and periocular injuries can cost the bird its sight if infection reaches the eyeball, decisively affecting release and quality of life. Crow-on-crow attacks are fierce, and persistent head shaking indicates pain or eye damage, so rest the bird in a dark box and see a vet the same day. The manual says attacks by other crows mean "even small wounds carry a high infection risk, so see a vet immediately." Human eye drops are not formulated for birds and mask symptoms, delaying diagnosis. Waiting a week gives infection time to spread. Feeding wild crows draws flocks and raises the risk of attacks and infectious disease (such as avian influenza).

IssuesThe roof was mesh only, so wild crows in breeding season could contact the kept bird. The basic requirement of considering the wild crows nearby was not met. Knowledge that wild crows defend territories and become aggressive in the March–July breeding season was lacking.

ImprovementCover the aviary roof with boards or sheet metal so wild crows and raptors cannot approach. Add screening on the sides to block sightlines. Watch the surroundings especially in breeding season, and if wild crows gather, review where food is placed and how calls are managed. Decide that an eye injury means a same-day vet visit and keep a transport box ready.

A December evening. At the evening feeding, a permitted large-billed crow (8 years old) cannot jump up to the perch and drags its left leg on the floor. The leg is swollen below the joint and the toes stay open, unable to grip. This morning it was on the perch as usual. There is a high perch in the aviary and it may have fallen during the day.

Which is the most appropriate first action?

1. Massage to reduce the swelling and pull the leg to straighten the joint
2. Put it in a dark box with no perch, do not touch the leg, and see a vet the same day
3. Crush a human fever reducer into the food as a painkiller until the pain subsides
4. It can walk, so it is not a fracture; wait a few weeks for it to heal on its own

AnswerB. Put it in a dark box with no perch, do not touch the leg, and see a vet the same day

ExplanationA swollen leg, inability to grip and inability to reach the perch suggest a fracture, dislocation or nerve damage; "dragging a leg, unable to get onto the perch" is a "same day" vet case. Do not touch the affected area; rest the bird in a dark box without a perch to prevent falls and see a vet the same day. Massage or pulling displaces bone fragments and damages nerves and vessels. Human fever reducers and painkillers are highly toxic to birds and can kill even in small doses. A bird can walk with a fracture, and left alone it may heal deformed and never perch again.

IssuesAn elderly bird was given a high perch, with no consideration of fall risk from injury or age. There was no daytime observation, so when and what happened is unknown. The idea of using human medicine for pain is also dangerous.

ImprovementFor elderly or injured birds, lower the perches and lay soft bedding on the floor to cushion falls. Check on the bird during the day as far as possible and install a monitoring camera. Agree as a family never to give human medicine. Keep a dark transport box and the hospital contact ready.

8 p.m. in October. A carrion crow rescued today on the wildlife office's instructions was resting in a cardboard box, but on checking, the skin is torn midway along the right wing and the white tip of a bone is showing. Bleeding is slight but the wound is starting to dry. The vet appointment is tomorrow morning, but the bird has its eyes closed, is limp, and is becoming less responsive.

Which is the most appropriate action now?

1. Wash the wound thoroughly with tap water, push the bone back, bandage it and wait until morning
2. Do not touch the wound; cover it lightly with clean gauze, keep the bird warm, and immediately contact and transport it to a hospital that handles after-hours cases
3. Crush a human painkiller finely, dissolve it in water and give it to relieve pain
4. Return it to the aviary until the appointment tomorrow and check whether it can fly

AnswerB. Do not touch the wound; cover it lightly with clean gauze, keep the bird warm, and immediately contact and transport it to a hospital that handles after-hours cases

ExplanationAn open fracture with bone showing falls under "bleeding that will not stop, visible bone" in the "call now" category; infection and tissue necrosis progress rapidly, so do not wait for tomorrow's appointment but find an after-hours hospital and transport the bird. Do not touch the wound; cover it lightly with clean gauze, keep warm in a dark box and carry it without jolting. Pushing the bone back or washing with tap water spreads infection and further damages bone fragments. Human painkillers are highly toxic to birds and must never be given. Back in the aviary, flying worsens the fracture and restarts bleeding. Limp and poorly responsive is a sign of shock: hurry while keeping it warm.

IssuesThe wing was not examined properly at rescue, and the open fracture was missed until night. Having booked a next-day appointment gave false reassurance and the urgency was not reassessed. Not knowing an after-hours hospital in advance could have delayed transport.

ImprovementAt rescue, restrain with leather gloves and a towel and check the wings, legs and head; decide that bleeding or exposed bone means an immediate vet visit regardless of appointments. Note the contacts for a hospital that sees wild birds and an emergency (after-hours) animal hospital. Prepare a transport box with air holes and a towel, have a heat source ready, and carry the bird dark and quiet.

A holiday morning in August. An elementary-school child went alone into the aviary of a permitted large-billed crow (4 years old) and leaned in close to hand it food; the bird jabbed the child's cheek with its beak and scratched below the eye with a claw. The cheek is bleeding, the area under the eye is swollen, tears will not stop, and the child is crying "my eye hurts." The crow is agitated and flying around the aviary.

Which is the most appropriate first action?

1. Get the child out of the aviary, rinse the wounds under running water, and because of the eye pain take the child immediately to an eye doctor or an emergency room
2. Catch the crow and punish it, put a bandage on the child and watch
3. Put in eye drops, cool the eye and wait until the next morning for the swelling to go down
4. Disinfect the wounds, then send the child back into the aviary to apologize to the crow

AnswerA. Get the child out of the aviary, rinse the wounds under running water, and because of the eye pain take the child immediately to an eye doctor or an emergency room

ExplanationCrows go for people's eyes, and wounds around the eye can lead to corneal damage and blindness. The manual states clearly: "Deep wounds or eye injuries: go to a hospital (for people) immediately." First get the child out of the aviary to prevent further harm, rinse the wounds under running water, and because of the eye pain go immediately to an eye doctor or emergency room. Bird claws and beaks carry many bacteria, so infection prevention is also needed. Punishing the crow achieves nothing; it will remember the person and the relationship will only worsen. Masking symptoms with eye drops or waiting until morning lets corneal injury and infection progress. Sending the child back into the aviary while the bird is agitated is out of the question.

IssuesSupervision was lax in letting a child enter the aviary alone, and the basic rule of not bringing your face close had not been shared with the family. Understanding that crows go for the eyes and are strong, highly intelligent and wary was insufficient.

ImprovementOnly adults wearing leather gloves and safety glasses enter the aviary, and design it so children cannot enter alone. Feed from outside the door and have the whole family confirm the rule of never bringing your face close. Decide in advance that human wounds are rinsed under running water and disinfected, and deep or eye wounds go to a hospital (for people) immediately.

A March afternoon. An adult large-billed crow just rescued on the wildlife office's instructions was being watched in a large plastic container on the floor of a bright living room. Every time someone approaches it thrashes and beats its wings against the container walls; feathers at the wing tip have broken and are bleeding, and several feathers have fallen out. Family members keep coming by in turns to look and take photos.

Which is the most appropriate first action?

1. Hold it down by hand so it cannot thrash and tape the wings to the body
2. Leave the container in the bright spot and have the family talk to it often so it gets used to people
3. Move it to a cardboard box with air holes lined with a towel in a dark, quiet room, reduce people coming and going, press the bleeding, and see a vet the same day
4. It is bleeding, so wash the wing with water and dry it with a hair dryer

AnswerC. Move it to a cardboard box with air holes lined with a towel in a dark, quiet room, reduce people coming and going, press the bleeding, and see a vet the same day

ExplanationA crow just after rescue is intensely wary and thrashes every time it sees a person, and in a bright, transparent container it repeatedly injures itself. The manual's basics are a "dark cardboard box lined with a towel" and resting "without stress"; reducing people coming and going and photography is the best prevention of self-injury. Press the bleeding with clean gauze, and see a vet the same day for the feather shaft damage. Holding it down and taping restricts breathing and damages feathers and skin. Frequent talking is counterproductive for a wary bird. Washing and blow-drying rob body heat and the hot air causes burns.

IssuesMultiple stressors were stacked: the rescued bird was put in a transparent container in a bright, busy spot and the family kept peering in and photographing. The knowledge that to a wild crow people are predators, and that a quiet, dark environment is the precondition for treatment, was missing.

ImprovementUse a rescue box made of material that blocks vision, such as cardboard, line it with a towel and place it in a dark, quiet room. One person does the care, briefly; no photos or spectators. Check breathing and posture quietly through the air holes. Keep gauze and leather gloves nearby, and if there is bleeding, apply pressure and see a vet.

A July morning. When you opened the aviary's inner door to feed, a permitted carrion crow (2 years old) at your feet got its left wing caught between the door and the frame. You opened the door at once, but it cannot hold the wing against its body; the wing hangs down and there is swelling at its base. The bird is hunched on the floor and does not try to fly. The aviary has no vestibule; the door opens directly to the outside.

Which is the most appropriate first action?

1. Spread the wing to check for a fracture, and return it to the aviary if there is none
2. Hold the wing against the body, wrap in a thick towel, put it in a dark box and see a vet the same day
3. Put it on a high perch in the aviary to rest until the pain passes
4. Press ice directly on the swelling and watch until tomorrow

AnswerB. Hold the wing against the body, wrap in a thick towel, put it in a dark box and see a vet the same day

ExplanationA wing that droops and swells after being caught in a door suggests fracture, dislocation or nerve damage; "drooping wing, unable to fly" is a "same day" vet case. The manual's first aid for wing fractures is "hold the wing against the body and wrap in a thick towel to restrain; do not touch with bare hands; see a vet the same day," and rest it in a dark box so it does not worsen things by trying to fly. Spreading the wing to check displaces bone fragments and worsens bleeding and nerve damage. A high perch invites a fall and secondary injury. Ice applied directly causes frostbite, and waiting until tomorrow makes the fracture harder to set.

IssuesBeyond the basic carelessness of not checking where the bird was when opening the door, the lack of a vestibule created a risk of door accidents and escapes. The manual says "close the vestibule door before opening the inner door and check where the bird is."

ImprovementAdd a vestibule to the aviary and always close the outer door before opening the inner one. Visually confirm the bird's position before opening the inner door, and wait if it is at your feet. Fit cushioning to the door edge to reduce impact if it is caught. Keep a dark transport box, towel and leather gloves near the aviary.

A November evening, cleaning the dim aviary. You did not notice a permitted large-billed crow (6 years old) foraging among dead leaves on the floor, stepped backward and trod on its leg. The bird squawked and leapt up, and is now hunched on the floor holding one leg up. When you try to touch it, it threatens you and moves away, apparently in pain.

Which is the most appropriate first action?

1. Handle the leg and flex it to check for yourself whether it is fractured
2. If it can threaten you it is fine, so let it roam the aviary
3. Without touching the wings or legs, cover its head with a towel, put it in a dark box, and see a vet the same day if it cannot walk
4. Brighten the aviary and keep watching until the pain passes, taking photos to consult a friend

AnswerC. Without touching the wings or legs, cover its head with a towel, put it in a dark box, and see a vet the same day if it cannot walk

ExplanationThe manual says "if stepped on, do not touch the wings or legs; put the bird in a dark box and see a vet if it cannot walk." Leg damage from being stepped on includes fractures and joint injuries, and an amateur flexing it to check displaces bone fragments and damages nerves and vessels. Threatening is a fear and pain response, not a sign of health. Left loose in the aviary it may fall from the perch and sustain secondary injury. Brightening the aviary to keep watching or sending photos to friends only adds stress; leave the treatment decision to the vet. Holding one leg up and unable to walk is a "same day" vet case.

IssuesThe cause was carelessly working in dim conditions without checking underfoot. Crows forage on the floor, so you must always know where the bird is when cleaning. There was no routine of moving the bird to a separate section during cleaning.

ImprovementClean and do other work in daylight, and check the bird's position before entering and during work. If possible, design the aviary so the bird can be moved to a vestibule or separate section during work. Confine the floor foraging area to a set spot away from your working path. Keep a dark transport box, towel and the hospital contact near the aviary.

7 a.m. in April. A permitted large-billed crow (5 years old) undid the aviary latch by itself and flew out the open door to a nearby utility pole. It can fly, but after years in captivity it has not learned to find food outdoors or deal with predators. A flock of neighborhood wild crows is starting to gather and calling threats. The family is about to grab a net and give chase.

Which is the most appropriate first action?

1. Run after it with a net and throw stones from under the pole to bring it down
2. Do not chase; report to the prefectural wildlife office, open the aviary door, lure it with the feeding spot and its usual calls, and wait for it to return
3. It can return to the wild, so treat it as released and stop keeping it
4. Ask the neighbors to shout all at once to startle it back into the aviary

AnswerB. Do not chase; report to the prefectural wildlife office, open the aviary door, lure it with the feeding spot and its usual calls, and wait for it to return

ExplanationThe manual says "if it escapes, report to the wildlife office and lure it back with the feeding spot and its calls. Do not chase." Chasing or throwing stones frightens it into flying far away and causes collisions with power lines or cars. A kept bird cannot adapt to wild life and is at high risk of attack by wild crows or starvation, so unilaterally treating it as released violates the permit conditions and is irresponsible. Driving it with shouting is also counterproductive. Open the aviary door, use familiar food and the owner's voice to lure it back on its own, and report to the wildlife office for instructions.

IssuesCrows are intelligent enough to open latches themselves, which is why the manual requires two padlocks. The cause was a lax setup relying on a single simple latch. The lack of a vestibule also allowed escape the moment the door opened.

ImprovementFit a vestibule to the aviary and padlock both the outer and inner doors. Check the locks daily, and if the bird is seen tampering with a lock, change its position or design. Keep the wildlife office contact on file and share the escape procedure (do not chase, lure with food and voice, report) with the family.

A June afternoon. A carrion crow in temporary care under permit, being treated for a wing fracture, was returned to a high perch in the aviary because it seemed to be recovering. A few hours later it is hunched on the floor, shaking its head side to side and squinting. The wing splint has slipped and there is a little blood at the edge of its beak.

Which is the most appropriate first action?

1. Rewrap the splint yourself, put it back on the perch and keep up the flying practice
2. It seems to have hit its head, so splash water on it to sharpen its awareness
3. Let it rest on the floor for a while and watch in the aviary until tomorrow's appointment
4. Move it to a dark box with no perch, do not touch the splint, keep it warm, and see a vet the same day for suspected head trauma

AnswerD. Move it to a dark box with no perch, do not touch the splint, keep it warm, and see a vet the same day for suspected head trauma

ExplanationThe manual states clearly that a bird with an injured wing cannot fly and will fall from height, and the rule is "lower the perches while injured." Head shaking, squinting and bleeding from the beak after a fall indicate head trauma or wounds inside the mouth, so see a vet the same day. Rewrapping a slipped splint as an amateur displaces the fracture again, and flying practice invites another fall. Splashing water robs body heat, risks aspiration and does nothing for a head injury. Waiting in the aviary until tomorrow risks progression of intracranial bleeding or shock. Keep it warm in a dark, quiet box and carry it without jolting.

IssuesThe cause was jumping the gun by returning a recovering bird to a high perch without the vet's judgment. The care of lowering perches and softening the floor for injured birds was missing. There was also no habit of checking the splint and fall risk daily.

ImprovementKeep a bird under treatment in a recovery space with low perches and a soft floor until the vet clears it to fly. Raise perch height gradually and watch for falls. Do not fix a slipped splint yourself; see the vet. Keep a dark transport box and heat source on hand.

Midday in August, an extremely hot day. You had filled a large, deep tub with water for a permitted large-billed crow (3 years old). Returning home, you found the bird half submerged in the tub with soaked feathers, struggling and unable to climb over the rim. You pulled it out at once, but it is limp, its body is cold, and it is breathing weakly with its mouth open.

Which is the most appropriate first action?

1. Blot the water off with a towel, put it in a dark box at around 30°C, and go to the vet immediately if breathing is weak
2. Blow hot air from a hair dryer at close range to dry the feathers quickly
3. Hold it upside down and shake it to expel swallowed water
4. Put it in the sun to dry naturally and return it to the aviary once it perks up

AnswerA. Blot the water off with a towel, put it in a dark box at around 30°C, and go to the vet immediately if breathing is weak

ExplanationWet feathers lose their insulation, and body temperature drops fast even in summer. First blot the water with a towel, then rest the bird warm in a dark box at around 30°C. Weak breathing or being limp and unable to get up is a "call now" case, and aspiration pneumonia is also a risk, so go to the vet immediately. Hot air from a dryer causes burns and overheating, and shaking it upside down damages the neck and organs and can trigger cardiac arrest. The sun on an extremely hot day causes heatstroke and is most dangerous for a bird with unstable body temperature. The manual's water guidance is a "deep, heavy container," but the depth and footing must let the bird get out on its own.

IssuesThe drowning was caused by a deep tub with a high, slippery rim and no footing to climb out. The owner was away for a long time on an extremely hot day and had not anticipated a bathing accident. The basics of designing bathing and drinking containers were not understood.

ImprovementMake the bathing container shallow, put a non-slip mat on the bottom, and provide a step or ramp to climb out. Keep the depth so the legs reach the bottom, and reduce the water when away. On extremely hot days ensure shade and ventilation and check with a monitoring camera. Share the drowning procedure (blot, warm, vet) and the hospital contact with the family.

A January night. A permitted large-billed crow (4 years old) out in the room under supervision chewed a heater's power cord with its beak the moment you looked away, and collapsed to the floor with a loud snap. The area around its beak is blackened, and its body is rigid and motionless. The cord is still plugged into the outlet.

Which is the most appropriate first action?

1. Pick the bird up with bare hands at once, pull it away from the cord and check its breathing
2. Unplug the cord first, then touch the bird, check breathing and responsiveness, and go to the vet immediately while keeping it warm
3. It is not moving, so assume it is dead and leave it until morning
4. Press hard on the chest with repeated cardiac massage and keep going until it responds

AnswerB. Unplug the cord first, then touch the bird, check breathing and responsiveness, and go to the vet immediately while keeping it warm

ExplanationTouching an electrocuted bird while the current is still live electrocutes the rescuer too. Unplug and cut the power first, then touch the bird and check consciousness (response to touch or sound, movement of the nictitating membrane) and breathing (chest rising and falling). Electric shock causes not only burns in the mouth but delayed arrhythmia and pulmonary edema, so even if it moves, do not relax: keep it warm and go to the vet immediately. Bare-hand contact risks secondary electrocution. Assuming death and leaving it abandons a bird that could be saved. Chest compressions in birds are not recommended due to fracture risk. Prioritize the airway and warmth, and if response is weak, hurry while keeping it warm.

IssuesThe rule for time indoors is "cover windows and mirrors and supervise," but chewable items such as cords were not cleared away and the bird was left unwatched. Understanding that crows are strongly drawn to shiny or long thin objects and test everything with the beak was lacking.

ImprovementBefore letting the bird indoors, cover or remove power cords and fit outlet covers. While it is out, one person keeps constant watch, with doors and windows closed and mirrors covered. Share the electrocution procedure (cut power, check, warm, vet) with the family and know an after-hours hospital.

A May evening. A visitor's large dog passing the garden aviary broke free of its leash, lunged at the mesh and kept barking. The permitted carrion crow (2 years old) flew around the aviary in panic, crashed into the mesh repeatedly, then dropped to the floor, breathing hard with its mouth open and lying with wings spread, motionless. No external injuries are visible.

Which is the most appropriate first action?

1. No injuries, so it will recover once the dog is gone; keep watching it in the aviary
2. Pick it up and stroke it to calm it, and put some water in its mouth
3. Get the dog completely away, move the bird to a dark box and keep quiet, and see a vet the same day if the open-mouth breathing continues
4. Spray water into the aviary with a mister and blow a fan on it to calm it down

AnswerC. Get the dog completely away, move the bird to a dark box and keep quiet, and see a vet the same day if the open-mouth breathing continues

ExplanationTo a crow, a charging dog is a predator attack in itself, causing internal bleeding or head trauma from collisions and shock from extreme stress. First get the dog completely out of sight, move the bird to a dark box, keep it quiet and warm, and see a vet the same day if open-mouth breathing continues or it is limp and cannot get up. Even without external injuries, collision impacts can damage organs or air sacs. Picking it up and stroking increases stress when people too are perceived as predators, and putting water in its mouth risks aspiration. Misting or fanning robs body heat and heightens fear.

IssuesThe principle of complete separation from other pets was not applied to a visitor's dog. The aviary sat on the garden's walkway where outside animals could approach. The unscreened mesh also let the bird see the dog directly, triggering panic.

ImprovementPlace the aviary away from the household's and visitors' routes and surround it with a fence or screening so other animals cannot approach. Tell visitors the rule that dogs are not allowed on the property. Line the inside of the mesh with fine netting to cushion impacts. After a panic, rest the bird in a dark box, watch its breathing and decide on a vet visit.

2 a.m. in March, an earthquake of seismic intensity 6-lower. Going out to the garden with a flashlight during the blackout, you find the metal aviary tilted and the mesh torn, and the permitted large-billed crow (7 years old) is nowhere to be seen. You hear its familiar call from a nearby tree but cannot tell where it is in the dark. The family is outside, afraid of aftershocks.

Which is the most appropriate first action?

1. Climb the tree in the dark to catch it and corner it so it cannot get away
2. It cannot be found, so give up on it as released, prioritize the family's evacuation and never look again
3. Secure the family's safety, wait for dawn, then lure it with the feeding spot and your voice in daylight and report to the wildlife office
4. Shout to the neighbors and throw stones toward the call to see if it reacts

AnswerC. Secure the family's safety, wait for dawn, then lure it with the feeding spot and your voice in daylight and report to the wildlife office

ExplanationIn a disaster, human safety comes first, and climbing a tree at night with aftershocks risks a fall. Crows are diurnal and do not move at night, so it will most likely stay nearby until dawn. The manual's escape rule is "report to the wildlife office and lure it back with the feeding spot and its calls; do not chase," so lure it near the aviary with familiar food and your voice once it is light. Cornering or throwing stones frightens it into flying far away, and a kept bird cannot survive outdoors. Abandoning it as released violates the permit conditions and is irresponsible. Prepare a temporary box or another enclosure before taking it back, since the aviary has collapsed.

IssuesThere was no earthquake anchoring for the aviary and no backup box to hold the bird temporarily if it broke. Lighting for blackouts and an evacuation procedure for the family and the bird had not been decided. The danger of searching at night and the crow's nighttime behavior were not understood.

ImprovementAnchor the aviary to a foundation and reinforce the mesh joints. Store a large carrier or cardboard box, leather gloves, a towel and food with the disaster supplies for temporary housing. Have a headlamp for blackouts. Share the disaster procedure (human safety, check the bird, report to the office, lure) with the family.

A February afternoon. A permitted large-billed crow (3 years old) playing in the room grabbed a small metal ring from the table and ran around with it. When you tried to take it away it made a swallowing motion, and now the ring is nowhere to be found. The bird looks fine so far, but you are not sure what the ring is made of.

Which is the most appropriate first action?

1. It looks fine, so wait for it to pass and check the droppings for a few days
2. Put a finger in its mouth to feel for it in the throat and pull it out if found
3. Give salt water to make it vomit and recover the ring
4. Search the room, including places it may have cached it, and if not found see a vet the same day for an X-ray

AnswerD. Search the room, including places it may have cached it, and if not found see a vet the same day for an X-ray

ExplanationCrows cache food and shiny objects, so it may not have swallowed it, but if it did, depending on the metal it can cause lead or zinc poisoning and sharp edges can damage the digestive tract. The manual says "swallows shiny objects and small metal items; green droppings or unsteadiness: see a vet," and for metal of unknown composition a same-day X-ray is the safe course. Poisoning progresses while you wait for it to pass. A finger in the mouth gets bitten and pushes the object deeper. Salt water does not induce vomiting in birds and risks salt poisoning and aspiration. Once poisoning signs (green droppings, unsteadiness) appear, treatment is already late.

IssuesThe basic step of clearing small metal and shiny objects before letting the bird indoors was neglected. The owner underestimated the crow's strong attraction to shiny objects and its habit of grabbing and swallowing or hiding them. Not knowing what the ring was made of made the risk impossible to judge.

ImprovementBefore letting the bird indoors, clear all small items from tables and shelves, including jewelry, button batteries and coins, and designate a dedicated play room. Fill playtime with safe twigs, pine cones and food-hiding puzzles. Decide that suspected swallowing means a same-day vet visit and keep the contact of a hospital that sees wild birds on file.

7 p.m. in December, at a family gathering. A guest, saying "it is so smart, it will eat anything," was feeding a permitted carrion crow (6 years old) avocado salad and pieces of chocolate through the mesh. You noticed and stopped it, but it has already eaten several mouthfuls. It looks fine now, and the guest says "a little is fine."

Which is the most appropriate first action?

1. It was a small amount, so watch and consider it fine if it is well tomorrow morning
2. Make it drink a lot of milk to dilute the poison and wait until tomorrow
3. Remove the rest, record the amount eaten and the time, and contact a hospital the same day for instructions before symptoms appear
4. Open its mouth and stimulate the throat with a finger to make it vomit, then return it to the aviary

AnswerC. Remove the rest, record the amount eaten and the time, and contact a hospital the same day for instructions before symptoms appear

ExplanationAvocado and chocolate are on the manual's list of forbidden foods, and in birds even small amounts cause breathing difficulty, arrhythmia, seizures and sudden death. It is often too late once symptoms appear, so record the amount and time, and contact a hospital that sees wild birds the same day for instructions before symptoms start. Watching until morning risks a sudden deterioration and death overnight. Birds cannot digest milk; it causes diarrhea and does not dilute poison. Stimulating the throat with a finger does not work in birds and causes aspiration and mouth injuries. Watch breathing and posture while seeking care.

IssuesThe causes were a setup where guests could feed human food through the mesh and a failure to tell guests which foods are forbidden. The understanding that a crow being omnivorous and eating anything is a separate matter from whether the food is safe had not been shared.

ImprovementPost a sign in front of the aviary reading "Please do not feed" with the forbidden foods listed, and brief guests in advance. Add a second barrier so hands cannot reach through the mesh. Keep human food, especially avocado, chocolate, onions and allium family, and salty or oily foods, away. Post the contact for accidental ingestion near the aviary.

A September morning. Yesterday you dropped a rubber band that had been around a food bag in the aviary of a permitted large-billed crow (2 years old) and left it there. This morning the band is nowhere to be seen, and the bird keeps picking up food and dropping it, stretching its neck and making swallowing motions. It has not passed droppings yet this morning.

Which is the most appropriate first action?

1. Watch the droppings for a while and increase food to push the band through
2. If it is visible in the throat, pull it out with fingers or tweezers
3. Give oil to lubricate and wait for it to pass naturally
4. Search the aviary, and if it is not found, see a vet the same day and describe the neck-stretching

AnswerD. Search the aviary, and if it is not found, see a vet the same day and describe the neck-stretching

ExplanationThe manual states clearly that crows "swallow shiny objects, small metal items and rubber"; rubber is not digested and causes intestinal obstruction or gets lodged in the esophagus. Neck-stretching and swallowing motions suggest a foreign body in the throat or esophagus, so see a vet the same day to have it checked. Increasing food to push it through worsens an obstruction. Pulling with fingers or tweezers can snap it and leave a piece deeper, injure the esophagus, and get you bitten. Oil does not move a foreign body and can cause aspiration pneumonia. First search the aviary and tell the vet the situation, including the possibility it was only cached.

IssuesThe cause was lax management, leaving a small object in the aviary. Crows mouth small objects, and the manual's rule to "clear all small items from the enclosure" was not followed. There was no habit of checking belongings after work.

ImprovementList what you bring into the aviary and check everything is in hand before leaving. Do not use rubber bands, string, plastic scraps or small parts inside the aviary. Open food bags outside the aviary. Share the signs of suspected swallowing (neck-stretching, dropping food, no droppings) with the family and decide on a same-day vet visit.

A November evening. You placed rodenticide in the shed next to the aviary of a permitted carrion crow (5 years old). A few days later, part of a dead rat was found carried into the aviary with signs the bird had eaten it. Today there is blood oozing around its mouth, blood in its droppings, and it is sluggish. There is no lead or other metal in the aviary.

Which is the most appropriate first action?

1. It is probably a mouth injury, so disinfect it and watch in the aviary until it heals
2. Report that it may have eaten a poisoned rat, note the product name and go to the vet immediately
3. Bleeding means iron deficiency, so feed extra liver
4. Put salt in its mouth to make it vomit the poison and give lots of water

AnswerB. Report that it may have eaten a poisoned rat, note the product name and go to the vet immediately

ExplanationMost rodenticides contain anticoagulants, and a bird that eats a poisoned rat suffers secondary poisoning. Bleeding from the mouth and in the droppings and sluggishness are the typical signs, and left untreated it dies of internal bleeding, so note the product name and ingredients and go to the vet immediately. Limpness and bleeding are "call now" cases. Assuming a mouth injury and merely disinfecting does not stop the bleeding tendency. Liver does not correct a clotting disorder and delays treatment. Salt in the mouth risks salt poisoning and aspiration, and vomiting is never induced in birds. Animal hospitals have antidote treatment, and early care raises survival.

IssuesPlacing rodenticide next to the aviary created a secondary-poisoning route via poisoned rats that the owner had not anticipated. Understanding of the crow's habit of pecking at carcasses was lacking. The aviary structure also let rats in through gaps.

ImprovementDo not use rodenticides or insecticides around the aviary; use physical traps and exclusion instead. Seal gaps in the aviary base and mesh to keep small animals out. Remove any carcass or unknown object brought into the aviary immediately. Decide that signs of suspected poisoning (bleeding, green droppings, unsteadiness) mean an immediate vet visit, and bring the product information.

A July morning. A family member who likes fishing had been giving a permitted large-billed crow (4 years old) leftover raw bait fish and raw meat of unknown origin every day for several days. This morning it has continuous watery droppings, sits fluffed and sluggish, and has what looks like vomited food residue around its mouth. The family member says a fishhook may have been left in the fish.

Which is the most appropriate first action?

1. Stop the bait and raw meat, report the possible fishhook with photos of the droppings, see a vet the same day and request an X-ray
2. It just has an upset stomach from raw food, so fast it on water only and watch for a few days
3. Mix a little human stomach medicine into the food to stop the diarrhea
4. Fresh raw meat will fix it, so increase the amount to build its strength

AnswerA. Stop the bait and raw meat, report the possible fishhook with photos of the droppings, see a vet the same day and request an X-ray

ExplanationThe manual forbids "too much raw meat; items of unknown origin such as fishing bait": stale food causes bacterial food poisoning, and bait carries the risk of hooks or lead causing digestive tract damage or lead poisoning. With diarrhea, vomiting and sluggishness and a hook not ruled out, see a vet the same day for an X-ray for foreign bodies and a fecal exam. Fasting for days advances weakness and dehydration and ignores the hook or lead problem. Human stomach medicine has unknown safety in birds and does not treat the cause. More raw meat worsens food poisoning.

IssuesFeeding was left to a family member who had not been told the danger of routinely giving raw meat of unknown origin and fishing bait. The basic that raptor or omnivorous-bird food is the staple and raw meat and fish are supplements had not been shared. Awareness of tackle contamination was also lacking.

ImprovementAgree as a family, and post on paper, that raptor or omnivorous-bird food is the staple twice daily, with small amounts of boiled egg, chicken breast, fruit and insects added. Never give fishing bait or raw meat of unknown origin. Give raw items fresh and in small amounts and remove leftovers promptly. Check the droppings daily and see a vet with photos if anything is abnormal.

3 p.m. in early August, 36°C. The outdoor aviary of a permitted carrion crow (4 years old) is in direct western sun, the bathing dish is empty and the drinking water has gone warm. The bird holds its wings away from its body, drooping, breathes fast and hard with its mouth open, and is hunched in a shaded corner. It is still responsive.

Which is the most appropriate first action?

1. Pour cold ice water over its head to cool it fast and return it to the aviary
2. Move it to a dark box in a cool room with fresh water, lightly wet the legs and under the wings with lukewarm water, and see a vet the same day if breathing does not settle
3. Point a fan at the aviary on high and go out
4. Leave it in the aviary to toughen it up to the heat

AnswerB. Move it to a dark box in a cool room with fresh water, lightly wet the legs and under the wings with lukewarm water, and see a vet the same day if breathing does not settle

ExplanationWings held away and open-mouth breathing are classic heatstroke, the result of western sun and no water in conditions far above the 28°C upper limit. First move it to a dark box in a cool room with fresh water, and lightly wet the legs and under the wings with lukewarm water to lower the temperature gradually. If breathing does not settle or it stays limp, see a vet the same day. Ice water causes shock from rapid cooling and wet feathers lose thermoregulation. A fan alone while you go out just blows hot air and misses deterioration. The idea of toughening it to heat is wrong: birds cannot sweat and shed heat poorly, and forcing them to endure it kills them.

IssuesThere was no shade or sun screening in the west-facing outdoor spot, and bathing and drinking water were neglected on an extremely hot day. The manual's "summer: prevent heatstroke with shade, bathing and ventilation" was not practiced. There was no habit of checking the daytime temperature.

ImprovementFit shade cloth or a roof to block western sun and ensure airflow. In summer check and change bathing and drinking water morning, noon and evening, and place frozen bottles wrapped in a towel. Install a thermometer in the aviary and move the bird indoors on days above 28°C. Share heatstroke signs and first response with the family.

10 p.m. in January, a blackout from heavy snow. A weak, recently rescued large-billed crow in temporary care (permit pending) was relying on an indoor heater for warmth. The room temperature is starting to fall below 10°C, and the bird is fluffed up, shivering, with eyes closed. There is no estimate for when power will return. You have disposable warmers, a hot-water bottle, blankets and cardboard boxes.

Which is the most appropriate first action?

1. Nothing can be done until the power returns, so wrap a blanket directly around the bird and wait until morning
2. Heat the room with the gas stove and keep the bird's box next to it overnight
3. Line a cardboard box with a towel, place towel-wrapped hot-water bottle or warmers against the sides to aim for around 30°C, cover the box with a blanket, monitor the temperature, and see a vet in the morning
4. Give warm milk to warm it up and wait for the heating to return

AnswerC. Line a cardboard box with a towel, place towel-wrapped hot-water bottle or warmers against the sides to aim for around 30°C, cover the box with a blanket, monitor the temperature, and see a vet in the morning

ExplanationA weak rescued bird cannot maintain its own temperature, and the manual calls for warming to around 30°C. In a blackout, line a cardboard box with a towel, place a towel-wrapped hot-water bottle or warmers against the sides or underneath so the heat source does not touch the bird directly, and cover the box with a blanket. Check with a thermometer to prevent overheating. A blanket wrapped directly around the bird crushes the insulating feather layer and restricts breathing. Using a gas stove as a heater risks carbon monoxide poisoning and fire, and birds are especially sensitive to gas. Birds cannot digest milk, and there is a risk of aspiration. In the morning, report the condition and see a vet.

IssuesWinter warmth depended solely on an electric heater with no backup for a blackout. Although warmth is a lifeline for a weak bird, how to use emergency heat sources had not been checked in advance. No thermometer was ready either.

ImprovementAssemble a blackout warming kit: disposable warmers, hot-water bottle, blankets, cardboard boxes and a thermometer. Always wrap warmers in a towel and place them where the bird cannot touch them. In a blackout, cover the box to hold around 30°C while keeping air holes to avoid overheating and suffocation. In winter keep a dark indoor shelter box ready at all times.

A September evening; an evacuation order has been issued as a large typhoon approaches. A permitted large-billed crow (5 years old) is in the garden aviary. Wind and rain are intensifying and the aviary roof looks ready to blow off. The shelter accepts pets, but you have not decided how to transport a large bird. You have a large carrier, cardboard boxes, towels and leather gloves. There are about 30 minutes before you must leave.

Which is the most appropriate first action?

1. The bird can fly and escape on its own, so open the aviary door and let it go
2. Restrain it with leather gloves and a towel, put it in a dark carrier with air holes lined with a towel, and evacuate together with food, water and the permit
3. Leave it in the aviary, rope down the roof, and do not come back until the typhoon passes
4. It would be a nuisance at the shelter, so leave it in the car with the windows shut and go to the shelter

AnswerB. Restrain it with leather gloves and a towel, put it in a dark carrier with air holes lined with a towel, and evacuate together with food, water and the permit

ExplanationThe owner is responsible for a permitted bird; releasing it violates the permit conditions, and a kept bird cannot survive outdoors. An aviary in a typhoon is at risk of collapse and flying debris, so if the shelter accepts animals, take the bird. The manual's transport rule is "cardboard box with air holes, lined with a towel; dark, warm, no jolting, carried quietly; bring leather gloves," and evacuation is the same. The permit will be needed as proof. Left in the aviary it has no escape if it collapses, and a car risks heat buildup and flooding. At the shelter, keep it in the dark box in a quiet spot and be considerate about its calls.

IssuesIn a typhoon-prone area, how to evacuate a large bird had not been decided in advance. Disaster planning was missing: the shelter's conditions, carrying the permit, and preparing a transport carrier. Wind-proofing of the aviary was also inadequate.

ImprovementKeep an evacuation kit together: a large carrier that can be darkened, towels, leather gloves, food and water, and a copy of the permit. Confirm the local shelter's pet policy and consider whether sheltering in the car is an option. Anchor the aviary roof and protect against flying debris. Rehearse the evacuation as a family once a year.

Late June, with humidity above 80% after days of rain. The outdoor aviary of a permitted carrion crow (3 years old) smells of mold; the dead leaves and newspaper in the hide box are damp and blackened, and white cottony growth is on the leftover food in the dish. The bird is still lively but occasionally makes a sneeze-like sound.

Which is the most appropriate first action?

1. Discard all damp bedding and food, replace with dry, ensure ventilation, watch its breathing and see a vet early if anything is abnormal
2. Spray chlorine mold remover inside the aviary to dehumidify and leave the bird in it
3. It is close to nature, so leave the dead leaves and wait for the rainy season to end
4. Humidity cannot be helped, so increase food and let it get through on strength

AnswerA. Discard all damp bedding and food, replace with dry, ensure ventilation, watch its breathing and see a vet early if anything is abnormal

ExplanationDamp bedding and moldy food are the main sources of aspergillosis; the manual says "never use damp bedding or moldy food; ventilate well" and "replace damp bedding immediately to prevent mold." Discard the damp items at once, replace with dry bedding, ensure ventilation, and watch for sneezing, open-mouth breathing or respiratory noise. See a vet the same day if breathing becomes abnormal. Spraying chlorine cleaner with the bird in the aviary damages the respiratory tract with irritant gas. Leaving the dead leaves keeps a breeding ground for mold. More food does not reduce mold exposure. The suitable humidity is 40–60%.

IssuesHumidity management in the rainy season was neglected and bedding was not changed more often. Leftover food was left to grow mold. The knowledge that a crow's respiratory system is vulnerable to fungi and that damp conditions trigger disease was not put into practice.

ImprovementIn the rainy season change bedding daily and limit dead leaves and soil to dry material in smaller amounts. Collect leftover food within a few hours. Place a hygrometer in the aviary and review ventilation and rain cover when it exceeds 60%. Move the bird to a separate section when cleaning, and return it only after cleaners have dried fully and the smell is gone.

5 a.m. in October, an earthquake of seismic intensity 5-upper. The metal garden aviary did not fall, but the perches have dropped and the food dish has rolled over. The permitted large-billed crow (6 years old) is crouched low in a corner of the floor, motionless, with its eyes wide open. No injuries are visible, but when approached it stays rigid and barely responds when called.

Which is the most appropriate first action?

1. Keep calling its name loudly so as not to startle it, then pick it up to calm it
2. It is not moving, so assume it is dead and start tidying up
3. Take it out of the aviary and release it in the garden to be safe from aftershocks
4. Confirm your own safety, quietly tidy the aviary, refit the fallen perches low, provide a dark hide box, and after some time check its responsiveness and for injuries

AnswerD. Confirm your own safety, quietly tidy the aviary, refit the fallen perches low, provide a dark hide box, and after some time check its responsiveness and for injuries

ExplanationCrouching motionless after an earthquake is a freeze response to intense fear, and without injuries most birds recover with time in a quiet environment. First secure your own safety, quietly clear fallen items, refit the perches low to prevent fall accidents, and provide a dark hide box so it can settle. Then check walking, wing symmetry, breathing and droppings, and see a vet if anything is abnormal. Loud voices and picking it up heighten fear and cause it to thrash and injure itself. Assuming a motionless bird is dead is a mistake. Releasing it in the garden violates the permit conditions, and a panicked bird will not come back.

IssuesThe perches and food dish were not secured and fell in the shaking, frightening the bird. No aviary inspection procedure for earthquakes or approach to the fear response had been decided. Rushing to touch a frozen bird also invites secondary harm.

ImprovementSecure perches and food dishes firmly and keep nothing in the aviary that could fall. Share the post-earthquake procedure (human safety, check aviary damage, tidy quietly, observe the bird) with the family. After a fear response, let it settle in a dark hide box, and see a vet if it is still unresponsive or not eating after half a day.

An April holiday. You swept out the aviary of a permitted carrion crow (4 years old), including dried droppings that had been left for some time, with a broom. You inhaled the dust that rose, and from the next day had a dry cough and fever. The cleaning was done bare-handed without a mask, and the tools were washed in the kitchen sink. A pregnant family member was in the aviary with you.

Which is the most appropriate first action?

1. Treat it as a cold with over-the-counter medicine and clean the same way next time
2. See a doctor and tell them you inhaled dust from bird droppings; from now on wet the droppings before cleaning, wear a mask and gloves, and keep immunocompromised people and pregnant women away from care
3. Assume the bird carries disease and dispose of it
4. Stop feeding the bird and stay away from the aviary until the cough stops

AnswerB. See a doctor and tell them you inhaled dust from bird droppings; from now on wet the droppings before cleaning, wear a mask and gloves, and keep immunocompromised people and pregnant women away from care

ExplanationInhaling dust from dried droppings transmits psittacosis (chlamydia) to people. The manual's prevention is "wet droppings before cleaning; ventilate and wear a mask; people with weak immune systems should not do the care." With fever and a dry cough, it is important to see a doctor and report the bird contact; without that, proper testing and treatment are delayed. Taking over-the-counter medicine and cleaning the same way leads to reinfection, and the danger is greater for pregnant women and the immunocompromised. Disposing of a permitted bird is not allowed, and infection is preventable with proper hygiene. Stopping feeding weakens the bird and solves nothing. Do not wash tools in the kitchen.

IssuesLeaving droppings to dry and then dry-sweeping bare-handed without a mask neglected the basics of zoonosis prevention. Washing tools in the kitchen and letting a pregnant woman into the aviary were also dangerous. No care roles or hygiene rules had been set.

ImprovementMist droppings with a spray bottle before cleaning, and always use a mask, gloves and ventilation. Change bedding daily and seal it for disposal. Wash hands with soap after care and wash equipment in a dedicated outdoor spot. Pregnant women, the elderly and the immunocompromised do not take part in care. If the owner develops fever or cough, tell the doctor about the bird contact.

Late January. You keep a permitted large-billed crow (5 years old) in a garden aviary. For several days you have heard that crows and ducks have been dying one after another in a nearby park, and this morning a wild crow was lying weak in your garden. Your child says "poor thing, let's rescue it" and is about to pick it up with bare hands. The kept bird is well so far.

Which is the most appropriate first action?

1. Stop the child from touching the wild bird, contact the prefectural wildlife office, avoid contact with the kept bird, continue care with gloves and a mask, and step up hygiene
2. Rescue the wild bird, put it in the aviary with the kept bird, keep it warm and wait for it to recover
3. Pick the wild bird up bare-handed, bag it and throw it out with household garbage
4. Open the aviary and let the kept bird go far away so it does not get infected

AnswerA. Stop the child from touching the wild bird, contact the prefectural wildlife office, avoid contact with the kept bird, continue care with gloves and a mask, and step up hygiene

ExplanationWild birds dying one after another in winter may indicate avian influenza, and the manual says "do not touch weak or dead wild birds with bare hands; contact the prefectural government; wear a mask and gloves." Transmission is through contact with the droppings and secretions of infected wild birds, so isolate the kept bird completely from wild birds, wear gloves and a mask during care, disinfect shoe soles and change clothes. Putting the wild bird in the aviary would certainly infect the kept bird. Picking it up bare-handed and throwing it out risks human infection and spread. Opening the aviary violates the permit conditions and throws the kept bird into the middle of the infection source.

IssuesDespite the serious news of mass wild bird deaths, biosecurity for the kept bird had not been tightened. A child was allowed to be in a position to touch a wild bird bare-handed. The family had not shared the rule that suspected avian influenza means reporting, not rescuing.

ImprovementIf wild birds die abnormally nearby, contact the wildlife office and confirm the information. Cover the aviary with a roof and fine netting so wild birds cannot approach, and place food and water where wild bird droppings cannot fall in. Do care in dedicated shoes and clothing with gloves and a mask, and disinfect shoe soles on entering and leaving. Teach children the rule not to touch wild birds.

An August evening. After changing the food dish and water bowl of a permitted carrion crow (3 years old), you started cooking dinner without washing your hands. The next day several family members complain of stomach pain, diarrhea and fever. The food dish is always washed in the kitchen sink, and the bird itself is well with normal droppings.

Which is the most appropriate first action?

1. The bird is well so it is unrelated; treat it as food poisoning with over-the-counter anti-diarrheals
2. The family sees a doctor and reports that food may have been prepared with hands that touched bird droppings; from now on wear gloves, wash hands with soap, and do not wash equipment in the kitchen
3. Giving the bird antibiotics will clear the family's symptoms, so ask the vet for medication
4. Wiping the kitchen with bleach is enough, so do not change the care routine

AnswerB. The family sees a doctor and reports that food may have been prepared with hands that touched bird droppings; from now on wear gloves, wash hands with soap, and do not wash equipment in the kitchen

ExplanationSalmonellosis is transmitted to people orally from hands that touched bird droppings, and the bird itself is often an asymptomatic carrier. The manual says "handle with gloves and wash hands with soap after care; do not wash equipment in the kitchen." For the family's stomach pain, diarrhea and fever, see a doctor, report the bird contact and get tested. Suppressing it with anti-diarrheals can delay clearance of the bacteria and worsen things. Giving the bird antibiotics does not cure the people, and medicating an asymptomatic bird is an unnecessary burden. Wiping the kitchen alone will not prevent recurrence if the same routine continues. The fundamental fix is hand-washing after care and a separate place to wash equipment.

IssuesThe minimum hygiene step of hand-washing between bird care and cooking was missing, and the habit of washing the food dish in the kitchen sink caused cross-contamination in the home. Knowledge that a healthy-looking bird can still carry Salmonella was lacking.

ImprovementWear gloves for care and wash hands with soap for at least 30 seconds afterward. Wash food dishes and water bowls outdoors or in a dedicated bucket, never in the kitchen. Change clothes after care or use a dedicated apron. Get regular fecal exams at the vet, and if family members develop digestive symptoms, tell the doctor about the bird contact.

A May afternoon. You are about to house a weak juvenile large-billed crow, rescued on the wildlife office's instructions, directly in the aviary of your permitted large-billed crow (4 years old), thinking "it will feel safer with company." The juvenile has not yet been examined by a vet, and small insects are visible on its feathers. The plan is to share the food dish and water bowl.

Which is the most appropriate first action?

1. They are the same species, so house them together and let the resident bird look after it to speed recovery
2. Isolate the juvenile in a dark box in a separate room, do not share equipment until the vet exam and deworming are done, and care for the resident bird first
3. Let the juvenile use the resident bird's bathing dish to wash off the insects, then house them together
4. The juvenile's insects are natural, so do not worry and let them eat from the same dish

AnswerB. Isolate the juvenile in a dark box in a separate room, do not share equipment until the vet exam and deworming are done, and care for the resident bird first

ExplanationRescued birds almost certainly carry external and internal parasites and may carry infectious diseases. The manual says "do not share equipment with other birds" and "have the vet run a fecal exam and deworm," and isolation is the rule. Moreover, crows hold territories as pairs, and the resident bird may attack and seriously injure the juvenile. Care for the healthy resident bird first and the rescued bird last, changing gloves and washing hands in between. Sharing the bathing dish directly transfers parasites and pathogens. Left untreated, the insects spread to the resident bird and cause anemia and dermatitis. Decide cautiously whether to introduce them only after the vet exam is complete and behavior has been observed.

IssuesThe anthropomorphic assumption that "company is reassuring" ignored the principles of quarantine and isolation. The risk of territorial attacks by crows and the danger of parasites and pathogens brought in by a rescued bird were underestimated. Sharing equipment was also planned.

ImprovementIsolate any new bird in a separate room at least until the vet exam and deworming are complete, and keep separate food dishes, water bowls and towels for each bird. Care for the resident bird first, with a glove change and hand-washing in between. Consult the vet about cohabitation, proceed in stages starting with contact through mesh, and stop if any aggression is seen.

6 a.m. in February. A permitted carrion crow (9 years old) is lying on the aviary floor and does not respond to calling or light touch. On close inspection the chest rises and falls slightly and the nictitating membrane moves slowly. Its neck is bent and bits of food are visible inside the beak. The body is cold, and last night was below freezing.

Which is the most appropriate first action?

1. Do cardiac massage with firm chest compressions for one minute and wait for a response
2. Put it in a dark box warmed to around 30°C, extend the neck to open the airway, remove the food from the mouth, and go to the vet immediately while keeping it warm
3. Splash cold water on its face and shake it to bring it round
4. Put it directly on an electric blanket on the highest setting to warm it

AnswerB. Put it in a dark box warmed to around 30°C, extend the neck to open the airway, remove the food from the mouth, and go to the vet immediately while keeping it warm

ExplanationEven with little response, chest movement and nictitating membrane movement mean the bird is alive, and the manual's resuscitation guidance is: chest compressions are not recommended due to fracture risk; first warm to around 30°C in a dark, quiet box; extend the neck to open the airway and remove anything from the mouth; if response is weak, go to the vet immediately while keeping warm. For a hypothermic, weakened bird, warmth and an open airway come first, and food in the mouth can cause choking. Chest compressions break the keel and ribs and injure the lungs. Cold water and shaking rob more body heat and injure the head and neck. Placing it directly on an electric blanket on high causes overheating and burns, and a sudden temperature change causes shock.

IssuesOn a below-freezing night the aviary had no windbreak or insulated hiding place, and an elderly bird became hypothermic. There was no system for checking the night temperature and the bird's condition. The resuscitation steps (warm, open the airway, vet immediately) had not been reviewed in advance.

ImprovementIn winter fit a windbreak and an insulated hide box, and move the bird indoors on nights forecast below freezing. Keep a warming box, warmers, a hot-water bottle and a thermometer on hand, and practice checking consciousness, breathing and heartbeat (responsiveness, chest movement, ear to the chest). Post the contacts for an after-hours hospital and the wildlife office near the aviary.

9 p.m. in July. A permitted large-billed crow (6 years old) has been sluggish since evening and you have been observing it in a dark box. Its breathing exceeds 60 per minute, and with an ear to the chest the heartbeat sounds very fast and irregular. Its mouth is not open, but its eyes are closed and its feathers fluffed. The nearby hospital that sees wild birds is closed, and the emergency (after-hours) animal hospital is 40 minutes away by car.

Which is the most appropriate first action?

1. Record the breathing and heart rates, carry it quietly in a warm dark box without jolting, and head for the after-hours hospital
2. Its mouth is not open, so it is not an emergency; wait until morning and go to the nearby hospital
3. Take it out of the box, hold it close to calm its breathing, and tap lightly over the heart
4. Post a video online and wait for opinions from knowledgeable people

AnswerA. Record the breathing and heart rates, carry it quietly in a warm dark box without jolting, and head for the after-hours hospital

ExplanationA crow's resting breathing rate is about 20–30 per minute and heart rate about 200–300; breathing more than doubled with an irregular heartbeat is a sign of a serious condition. Fluffed feathers with eyes closed is also classic deterioration, and the risk of sudden collapse while waiting until morning is high. Record the breathing and heart rates to tell the vet, carry the bird quietly in a warm, dark box without jolting, and head for the after-hours hospital. A closed mouth does not rule out an emergency. Holding it close or tapping the chest restricts breathing and risks fractures. Posting online and waiting for opinions only loses time for treatment.

IssuesThe bird was sluggish from evening, yet the decision to seek care was put off until night. Not knowing the normal resting breathing and heart rates made it impossible to judge how serious it was. The location of the after-hours hospital had not been checked and transport was not prepared.

ImprovementMeasure and record the resting breathing rate (about 20–30 per minute) and heart rate (about 200–300) when the bird is well. Make it a habit to contact the hospital during opening hours if anything is off in the evening. Note the after-hours hospital contact and route, and keep a transport box and heat source ready to load into the car.

11 p.m. in November. A permitted carrion crow (4 years old) caught its leg in a tear in the aviary mesh and is bleeding from the top of the leg. You pressed with clean gauze, but after 5 minutes blood is still seeping and spreading on the newspaper. The bird is starting to go limp. The after-hours hospital is 30 minutes away by car. You have a towel, gauze, cardboard boxes and leather gloves.

Which is the most appropriate first action?

1. Remove the gauze, wash the wound with water, dry it and apply an adhesive bandage
2. Tie a rubber band tightly around the top of the leg to stop the blood and wait until morning
3. Keep pressing, wrap the bird in a towel, keep it warm in a dark cardboard box, and transport it immediately while calling the hospital
4. Pack flour or cornstarch into the wound as a styptic and return it to the aviary

AnswerC. Keep pressing, wrap the bird in a towel, keep it warm in a dark cardboard box, and transport it immediately while calling the hospital

ExplanationThe manual's bleeding procedure is "press with clean gauze for 5 minutes or more" and "if it will not stop, keep pressing on the way to the vet." A crow is small with little blood volume, so bleeding that does not stop after 5 minutes of pressure is life-threatening, and once it starts going limp it is a "bleeding that will not stop" case in the call-now category. Keep pressing, wrap the bird in a towel, keep it warm in a dark cardboard box, call the hospital and transport it immediately. Removing the gauze and washing flushes away the forming clot and restarts bleeding. A rubber band tourniquet causes the leg to die, and it may bleed to death before morning. Flour and cornstarch are sources of infection, and back in the aviary it will move and bleed again.

IssuesThe tear in the mesh was left unrepaired, leaving a hazard for catching a leg. Transport preparation for night bleeding (box, warmth, hospital contact) was not in place, and the limits of pressure and the threshold for seeking care were not understood.

ImprovementCheck the mesh for tears and protrusions in the daily inspection and repair them the same day. Keep clean gauze, a towel, leather gloves, a cardboard box with air holes and a heat source together in one box near the aviary. Decide that bleeding means 5+ minutes of pressure and an immediate vet visit if it does not stop, and share the after-hours hospital contact and route with the family.

A September afternoon. To take a permitted large-billed crow (3 years old) with a drooping wing that can no longer fly to the hospital, the family put it in a transparent plastic container on the back seat and are driving. The bird reacts to the scenery outside and thrashes in the container, tumbling with every hard brake. The driver says "it will be fine if we get there fast" and is speeding up.

Which is the most appropriate first action?

1. Open the windows for fresh air and turn the music up to settle the bird
2. Pull over, cover the container with a towel or cloth to darken it, secure it to the seat and drive gently without jolting
3. Speed up to arrive sooner and let the bird put up with the thrashing
4. Take it out of the container and hold it on a lap in the passenger seat, restraining it by hand

AnswerB. Pull over, cover the container with a towel or cloth to darken it, secure it to the seat and drive gently without jolting

ExplanationThe manual's transport rule is "dark, warm, no jolting, carried quietly." In a transparent container with a view outside, a wary crow thrashes and worsens the wing damage, and tumbling in sudden jolts causes fractures or head trauma. Pull over safely, cover the container with cloth to darken it, secure it to the seat and drive gently. Open windows and music add stimulation. Speeding up increases jolting and the risk of an accident. Holding it on a lap and restraining by hand is extremely dangerous: the person may be bitten if it thrashes, the bird may get loose in the car, and both may be badly hurt in a crash. Keeping it dark and unjolted saves lives more than arrival time.

IssuesA transparent container was used with no way to darken it and no securing to the seat. The decision to speed up out of urgency was dangerous for both bird and people. The transport basics (dark, warm, no jolting, bring leather gloves) had not been reviewed in advance.

ImprovementPrepare a cardboard box or carrier with air holes lined with a towel for transport, with a cloth to cover it from outside. Secure it to the seat in the car and avoid sudden starts and braking. Always bring leather gloves and a towel. Call the hospital before leaving to give the expected arrival time and condition.

Midnight in January. A carrion crow rescued on the wildlife office's instructions, due at the vet tomorrow, was being kept warm indoors in a cardboard box. Looking through the air holes, you see it breathing laboriously with its mouth wide open, neck stretched and whole body heaving. Each breath makes a wheezing sound. The after-hours animal hospital is 50 minutes away by car, but you do not know whether it sees wild birds.

Which is the most appropriate first action?

1. The appointment is tomorrow, so wait until morning and go as planned
2. Call the after-hours hospital to confirm it accepts wild birds; if so, transport the bird quietly while keeping it warm, and if not, try the wildlife office's emergency contact or another hospital
3. Take it out of the box and let it run around the room for ventilation to ease breathing
4. Put a finger in its mouth to feel whether something is stuck

AnswerB. Call the after-hours hospital to confirm it accepts wild birds; if so, transport the bird quietly while keeping it warm, and if not, try the wildlife office's emergency contact or another hospital

ExplanationLabored open-mouth breathing is a "call now" case in the manual, and waiting until tomorrow risks death from choking or sudden collapse. First call the after-hours hospital to confirm it accepts wild birds, and if so, transport the bird quietly in the warm, dark box. If not, try the wildlife office's emergency contact or another hospital. Letting it out to run raises oxygen demand, fear worsens the breathing further, and it may crash into things. A finger in the mouth gets bitten and pushes any foreign body deeper. Removing an object from the mouth is limited to carefully clearing something visible as part of opening the airway. Keep the warmth going while calling and transporting.

IssuesAt rescue, a night-time deterioration was not anticipated, and no after-hours hospital that sees wild birds or emergency contact for the wildlife office had been checked. During the period right after rescue, when respiratory signs are common, breathing was not observed more frequently.

ImprovementOn the day of rescue, confirm a hospital that sees wild birds, whether it has after-hours cover, and how to reach the wildlife office in an emergency. For the first few days after rescue, check breathing rate and posture through the air holes every few hours. Decide that open-mouth breathing, respiratory noise or a stretched neck means calling regardless of the hour.

A June morning. A permitted large-billed crow (5 years old) is lying on its side on the floor instead of on the perch. It does not move when called, and the family is in an uproar saying "it's dead." It does not fly up when approached, but the body is still warm. You do not know what to check or how to judge.

Which is the most appropriate first action?

1. Pinch the legs, lift it and let it dangle to see if it moves
2. Pour water over the whole body to see if it reacts
3. Judge it dead and start preparing to bury it in the garden
4. Approach quietly, check its response to touch and sound, nictitating membrane movement, chest movement, and the heartbeat with an ear on the chest; if there is any sign of life, keep it warm and go to the vet immediately

AnswerD. Approach quietly, check its response to touch and sound, nictitating membrane movement, chest movement, and the heartbeat with an ear on the chest; if there is any sign of life, keep it warm and go to the vet immediately

ExplanationThe manual's checks are: consciousness (response to touch or sound, movement of the nictitating membrane), breathing (watch the chest rise and fall; about 20–30 per minute at rest), heartbeat (ear on the chest; about 200–300 per minute). A warm body means it is very likely alive, and even if response is weak, if there is breathing or a heartbeat, put it in a dark box warmed to around 30°C, open the airway and go to the vet immediately. Pinching the legs and dangling it causes fractures and dislocations and worsens shock. Pouring water robs body heat and risks aspiration. Declaring death without checking is the gravest mistake, abandoning a bird that could be saved; always have a vet confirm before burying.

IssuesThe family did not know the basic checks for judging life or severity and panicked at the sight of a motionless bird. They had never measured the normal breathing or heart rate, so had no baseline for comparison. They rushed to a conclusion before considering the cause of the collapse (poisoning, injury, illness).

ImprovementPractice checking nictitating membrane movement, chest movement and the heartbeat with an ear on the chest while the bird is well, and record the baseline figures. Agree as a family that a collapsed bird is handled in the order check, warm, open the airway, vet immediately. Keep the transport box, heat source, leather gloves and the hospital and wildlife office contacts together in one place.
