Companion birds, particularly parrots, have complex social, cognitive, and behavioural needs that most domestic environments fail to meet, creating widespread but invisible welfare problems.
Companion parrots are wild animals in captivity, even when captive-bred. Their evolved needs — vast cognitive stimulation, constant social contact, extensive foraging activity, and complex communication — cannot be met by even the most dedicated human owner in a domestic environment. The behavioural consequences are widespread: feather-destructive behaviour, screaming, aggression, and stereotypies are common in single-housed parrots with inadequate stimulation. The welfare problem is compounded by the long lifespan of parrots, which creates a chronic situation rather than an acute one, and by the frequency of re-homing, which adds repeated social disruption to environmental deprivation. The most welfare-positive approach is to house parrots in large aviaries with conspecific companions, provide extensive foraging enrichment, and accept that the needs of large parrots cannot be adequately met in most domestic settings.
