Feather plucking — when a bird pulls out its own feathers — is one of the most distressing problems for pet-bird owners. It is almost always a sign that something is wrong, either physically or emotionally.
Emotional and environmental causes
Many pluckers are stressed, bored or lonely. Birds are intelligent and social, and too little attention, stimulation or sleep, a cramped or wrongly lit cage, or a change in routine can all trigger plucking. In these cases feathers are pulled as a way of coping — a little like nail-biting in people.
Physical causes
Plucking is just as often physical. Skin irritation, a poor all-seed diet, low humidity and dry skin, parasites such as mites, infections, allergies, hormonal changes, or an underlying illness can all make a bird pull at its feathers. This is exactly why a vet check matters — the cause is often not obvious.
What to do about it
Start with an avian vet to rule out medical causes. Alongside that, improve the basics: a varied diet of pellets and vegetables, more out-of-cage time and enrichment, proper sleep in a dark, quiet space, and, where relevant, more humidity or bathing. Never punish a plucking bird — it adds stress and makes things worse.
