Pet birds are frequently housed in cages too small to allow flight, causing physical deconditioning and psychological frustration. Evidence-based bird keeping prioritizes flight opportunities as a core welfare need.
Pet birds are among the most commonly compromised companion animals because their fundamental need for flight is structurally difficult to provide in domestic settings. A bird in a standard cage cannot take a single full wingbeat. Beyond flight, social species kept alone suffer from loneliness that is expressed through feather plucking, excessive vocalization, and behavioral abnormalities. Responsible bird keeping requires genuine commitment to daily flight opportunities, appropriate social housing, and species-specific environmental enrichment.
