Feather destructive behaviour in captive parrots is a complex welfare problem rooted in psychological stress, inadequate stimulation, and unmet social needs in species evolved for rich social and environmental complexity.
Parrots engaging in feather destructive behaviour are expressing chronic psychological distress through a behaviour that is absent in wild conspecifics. The behaviour itself causes further harm through skin damage, infection risk, and abnormal social signalling. Underlying causes including inadequate space, social isolation, barren environments, and inappropriate human bonding patterns must be addressed rather than just the feather damage itself. The long-lived nature of parrots means inadequately stimulated birds may suffer for decades.
