Wing clipping in companion birds is a contested practice with significant welfare implications, with evidence suggesting flight is important for both physical and psychological health.
Wing clipping eliminates one of the most fundamental abilities of birds - flight - for management convenience rather than demonstrated welfare benefit. Birds that cannot fly are prevented from expressing fear responses and escape behaviour, making them appear calmer while potentially experiencing higher chronic stress. The alternative approach of bird-proofing the home environment and harness training requires more initial effort but maintains the bird's physical and psychological integrity. Welfare organisations increasingly discourage routine wing clipping as a standard management practice.
