Budgerigars, cockatiels, and small parrots are among the most commonly kept birds yet are frequently housed in cages too small to allow flight, causing chronic welfare deficits.
Small parrots and parakeets are among the most chronically welfare-compromised companion birds due to the gap between typical housing and their actual needs. Budgerigars evolved as highly mobile flock animals that fly kilometers daily across grassland landscapes. Housing them in single-bird small cages denies both flight and social contact simultaneously, creating chronic deprivation. The welfare improvement available through paired housing with daily free-flight time in a bird-safe room transforms these birds' behavioral and physiological state dramatically. Small birds are often treated as low-maintenance because they are small, but their behavioral needs are no less complex relative to their ecology than larger parrots.
