Parrot Feather-Destructive Behaviour

Feather-destructive behaviour (FDB) in parrots is a serious welfare indicator requiring a thorough medical and behavioural investigation.

Key Facts

FDB affects up to 10% of captive parrots and encompasses feather plucking, chewing, and barbering.
Medical causes include skin infections, internal parasites, nutritional deficiencies, and heavy metal toxicity.
Psychological causes include boredom, social isolation, inappropriate human bonding, and anxiety.
African Grey parrots, cockatoos, and Amazons are most commonly affected.
Once established, FDB is difficult to resolve; multi-modal treatment is typically required.

Welfare Considerations

FDB is both a sign of poor welfare and a cause of further welfare compromise. Damaged feathers impair thermoregulation and flight; self-inflicted wounds can lead to serious infections. The behaviour often indicates that the bird's complex social, cognitive, and physical needs are not being met. Parrots are highly intelligent animals that require large amounts of stimulation, social interaction, and opportunities for natural behaviour. Single-bird ownership without adequate enrichment and foraging opportunities is a common predisposing factor. Treatment must address underlying causes rather than simply attempting to suppress the behaviour.

What You Can Do

Have any parrot showing FDB examined by an avian vet to exclude medical causes.
Provide extensive enrichment including foraging, novel objects, and social interaction daily.
Consider whether your parrot would benefit from a compatible avian companion.
Consult a certified parrot behaviour consultant if behavioural causes are identified.
