Large parrots including macaws and cockatoos require extensive flight opportunities for physical health; permanent full-wing clipping denies a fundamental natural behavior.
Wing clipping is widely practiced to restrict parrot flight for safety, but the welfare cost of permanent flight restriction in large parrots is significant. Flight is not merely locomotion for these birds - it is the primary exercise modality that maintains cardiovascular and muscular fitness. Permanently clipped parrots develop muscle weakness and obesity that compound age-related health decline. Training-based approaches that teach flight recall and establish safe indoor environments allow birds to be flighted while managing the real safety concerns that motivate clipping. The welfare benefit of flight exceeds the management benefit of clipping for most large parrot species.
