Small companion birds including finches, canaries, and budgerigars are popular worldwide but frequently kept in conditions that prevent expression of their natural behaviors, particularly flight and social interaction.
Small companion birds are frequently kept in conditions that prevent the most fundamental expression of their natural behaviors — flight. Cages sized to allow only short hops rather than sustained flight prevent exercise, cause musculoskeletal problems, and deprive birds of the behavioral satisfaction of free movement. Social species in isolation suffer from lack of conspecific interaction. Welfare standards for small birds have lagged behind those for parrots and other cognitively complex species, despite evidence that finches and other small birds have welfare needs that deserve comparable attention.
