Feather destructive behaviour in parrots and other companion birds is a complex welfare problem indicating significant psychological distress. Prevention and treatment require addressing underlying causes.
Feather destructive behaviour is one of the clearest welfare distress signals available in companion birds. Its presence indicates that the bird's psychological or physical needs are not being adequately met. Prevention is far more achievable than treatment - birds in species-appropriate social groups with rich environments and foraging challenges rarely develop FDB. Treatment of established FDB requires comprehensive assessment identifying any medical contributors, environmental modifications to increase enrichment and social opportunity, and patience. Some birds develop FDB that persists as a fixed pattern despite welfare improvement. The welfare implications extend beyond the behaviour itself to the chronic distress state underlying it.
