Feather destructive behavior in parrots is a complex welfare problem with multiple causes requiring individualized assessment and management.
Parrots that feather-pluck or mutilate themselves are expressing significant welfare compromise from medical, nutritional, or psychological causes. Physical collars preventing feather access do not address underlying causes and add to stress. Comprehensive veterinary assessment to rule out medical and nutritional causes before behavioral intervention is essential. Psychological causes require environmental enrichment and behavioral modification.
