Birds of prey kept in zoos and falconry settings have strong behavioral needs for flight that create significant welfare challenges in captive environments, with flight aviaries, flying demonstrations, and free flight opportunities varying widely in welfare quality.
Raptor welfare in captivity depends fundamentally on flight opportunities. Birds tethered for extended periods develop musculoskeletal problems, feather damage, and behavioral indicators of chronic stress. Large aviaries that allow free flight provide welfare improvement but cannot replicate the distances and complexity of natural flight behavior. Educational flying programs that provide regular free flight for cooperative birds represent a welfare-positive approach when managed to minimize crowd stress. The welfare standard for captive raptors should require meaningful daily flight opportunities rather than treating flight as an optional enrichment.
