Pet birds — from budgerigars to African grey parrots — have complex social, cognitive, and physical needs that are frequently unmet in domestic settings. Understanding and addressing these needs is essential for their welfare.
Companion bird welfare is complicated by the mismatch between the complexity of birds' needs and typical domestic environments. Even well-intentioned owners frequently provide inadequate space, social interaction, foraging stimulation, and species-appropriate companionship. Solitary housing of highly social flock species — most parrots, cockatiels, and finches — causes chronic psychological distress expressed through feather destruction, excessive vocalisation, aggression, and stereotypic behaviour. The cognitive demands of parrots are particularly challenging: without sufficient stimulation, they develop behavioural problems comparable to those seen in primates in impoverished environments. The keeping of large parrots as pets is increasingly questioned by avian welfare scientists, who argue that the welfare bar is beyond what typical owners can realistically meet.
