Feather Plucking and Overpreening in Companion Birds

Feather-destructive behaviour in companion birds is a serious welfare problem driven by stress, boredom, medical conditions, and social deprivation.

Key Facts

Feather-destructive behaviour affects an estimated 10-15% of companion parrots and many other captive bird species
Causes include skin conditions, internal disease, nutritional deficiency, psychological stress, and social isolation
African grey parrots, cockatoos, and Amazon parrots are disproportionately affected due to their high intelligence
Behavioural causes are often triggered by inadequate environmental enrichment and insufficient social interaction
Diagnosis requires ruling out medical causes before addressing behavioural interventions
Stress-related feather destruction can begin within weeks of environmental change or social loss

Welfare Considerations

Feather-destructive behaviour signals significant psychological distress in companion birds and indicates that their welfare needs are not being met. Birds that pluck or chew their feathers are often chronically understimulated, socially isolated, or experiencing untreated medical conditions. Effective management requires veterinary diagnosis, environmental enrichment, increased social contact, and sometimes pharmaceutical support. Prevention through species-appropriate husbandry is far preferable to treatment.

What You Can Do

Research the comprehensive care requirements before acquiring any companion bird
Provide companion birds with species-appropriate enrichment, foraging opportunities, and social contact
Seek avian veterinary assessment promptly if a bird begins feather-destructive behaviour
Support campaigns for minimum welfare standards in the companion bird trade and breeding industry
