Companion birds including budgies, cockatiels, and finches have complex needs that are often poorly understood by their owners, leading to significant welfare deficits.
Companion bird welfare is compromised by a combination of underestimated complexity and under-resourced care. Birds appear less expressive than mammals, making their welfare problems less visible, but their needs are no less real. The cage sizes typically sold and considered acceptable for small birds prevent any meaningful flight, a fundamental movement mode that cannot be substituted. Social species including budgies, cockatiels, and lovebirds kept alone experience loneliness that manifests in excessive vocalization, feather destruction, and apathy. The longevity of many bird species - cockatiels can live 20+ years - creates a multi-decade welfare commitment that owners frequently underestimate. Provision of appropriate social companions, sufficient out-of-cage time, and species-appropriate enrichment are essential welfare requirements.
