Feather-Destructive Behavior
What is it?
Feather-destructive behavior means a bird pulls, chews, or barbers its own feathers. Causes include medical issues (infection, parasites, liver disease, allergies) and behavioral or environmental stress such as boredom, loneliness, or hormonal frustration.
What signs should I watch for?
Signs to watch for include feather loss or patchy feathers, chewed or frayed feathers, self-injury to skin, and increased preening.
How is it diagnosed and treated?
A thorough exam and testing rule out medical causes first. Care then focuses on enrichment, foraging, diet improvement, sleep, and behavior changes.
Can it be prevented, and what's the outlook?
- It can take time to resolve, and some birds never fully stop.
- Early attention gives the best results.
