Feather destructive behaviour in captive parrots is a serious welfare indicator affecting a significant proportion of the captive parrot population worldwide.
Feather destructive behaviour is both a welfare indicator and a welfare problem: it signals underlying distress or pathology and causes ongoing physical harm if unchecked. The causes are diverse — skin parasites, fungal infections, nutritional deficiency, and psychological distress from boredom, grief, fear, or frustration can all manifest as FDB. A common mistake is treating the symptom physically, such as fitting collars that prevent access, without identifying the cause. This suppresses the behaviour while leaving the underlying welfare problem unresolved. Comprehensive investigation — veterinary examination to rule out medical causes, review of diet, environment, and social situation — is necessary for effective welfare-improving treatment. FDB that cannot be resolved with environmental and medical management requires referral to an avian behaviour specialist.
