See an avian vet at the first sign
The Association of Avian Veterinarians (AAV) says a bird should be seen at the first sign of feather picking, to rule out a potentially serious medical problem. Merck says to call it behavior only after a complete evaluation has excluded as many medical causes as possible. So do not start with a toy or a spray. Start with the vet. Skin sores or wounds need a vet as soon as you can.

First question
Is my bird molting or plucking?
Normal molt
- Slow and gradual, with most feathers replaced at least once a year, and often a partial molt about 6 months later
- Timing varies with diet, sunlight, day length and humidity
- Feathers on the cage floor are generally whole
- Does not usually show down or bare skin
Plucking or chewing
- Feathers can be shredded or chewed
- Bare patches, or down and skin showing
- An unusual number of feathers or feather pieces on the cage floor
A molt that seems to drag on is also a reason to see your avian vet. No source gives a set number of weeks, so ask.

Causes
What causes feather plucking in birds?
Medical causes: your vet checks these first
- Illness. Liver and kidney failure, tumors, airway infections and other illnesses can cause pain and stress that lead to plucking.
- Poor diet. Merck calls malnutrition likely one of the most common factors. See what parrots eat.
- Gut parasites, especially giardia in cockatiels. Swallowed zinc has also been suggested.
- Arthritis pain in older birds can show as picking.
- Loss where your bird cannot reach, such as the top of the head, can be a sign of disease, or a cage mate chewing.
Contrary to popular belief, mites are rarely the cause. So do not reach for a mite treatment.

Behavior causes: after the exam
Merck lists boredom, sexual frustration, territorial behavior, compulsive behavior, poor preening training, and stress from fear of predators such as household pets. Cage mates can also chew each other’s feathers.
In one owner survey in Japan, cockatoos had the highest rate. In one US hospital study, females and older birds had higher odds. These are single studies, not rules.

What helps
How do I stop my bird plucking its feathers?
- Do not reward plucking with attention or scolding.
- Separate cage mates if one bird is pulling another’s feathers.
- Do not give any remedy your vet did not prescribe.
- Keep a bare bird warm. Birds with feather loss get cold more easily, so keep the room warm and move the cage away from drafts.
- Follow your vet’s plan: food, enrichment and foraging all play a part.
- Take notes or a video of what happens before, during and after, and a photo a week from the same angles.
Be realistic. Merck’s goal is better health and less plucking, “if possible.” It may not stop completely.

First aid
What do I do about a broken blood feather?
First aid, step by step
A blood feather is a new, growing feather with its own blood supply. Its base looks cloudy and purple or red. Bleeding that does not stop is an emergency. Go to an avian vet now.
- Press gently with clean gauze or cotton. Never press on the chest, because that makes it hard for your bird to breathe.
- Styptic gel may help. Use it on the feather only, not on skin or an open wound.
- Do not use powders your bird could breathe in.
- Do not pull the feather at home, and do not cut it.
- Once the bleeding stops, leave the clot alone, and see an avian vet as soon as possible.
- If it bleeds again or does not stop, go now.
No source tells owners exactly how to treat a broken blood feather. The press, gel and do-not-pull steps are our own advice, the same as the app’s.

What the app logs
- Date, body area and how bad: chewed tips, chewed down to the skin, or pulled out with a bare patch
- Skin sores, wounds or bleeding marked, which moves the status to urgent
- When a molt starts and ends, and when an avian vet last checked the feathers
- Loss on the head gets its own note, because your bird cannot reach there
- First aid for a broken blood feather on the same screen, and the log goes into the vet report
