Cockatiels are highly social birds with complex needs that are frequently poorly met in single-bird captivity, leading to significant welfare problems.
Single cockatiels without adequate human social interaction or companion birds experience chronic loneliness that manifests in feather plucking, repetitive vocalisations and contact-seeking behaviour. Their social needs are comparable to those of other flock-living species and cannot be adequately met by sporadic human interaction around working hours. Responsible cockatiel ownership requires realistic assessment of time commitment, consideration of pair housing, and provision of appropriate diet, enrichment and veterinary care throughout their lengthy lifespan.
