Companion birds from canaries to macaws face welfare challenges that range from inadequate cage size to inappropriate diet and social deprivation that undermine their complex needs.
Companion bird welfare encompasses an enormous range of species with very different behavioral and physiological needs, united by the common challenge that most companion bird keeping practices developed before welfare science established what birds actually require. Budgerigars in small cages that cannot fly, canaries kept alone without flock companions, parrots on seed diets deficient in essential nutrients — all represent welfare deficits that result from outdated care practices and insufficient pre-purchase education. The long lifespan of many companion birds means that welfare deficits imposed in youth may persist for decades. The welfare standard for companion birds should be species-appropriate: social housing for social species, adequate flight space for aerial species, nutritionally complete diets for all, and veterinary care from avian specialists with the knowledge to recognize and treat bird-specific conditions.
