Parrots and other companion birds evolved to spend most of their waking hours foraging - enrichment that simulates this activity dramatically improves welfare.
Foraging deprivation is one of the most significant welfare problems in companion bird keeping, yet it receives little attention compared to more visible welfare failures. When birds receive food in bowls, their primary daily occupation disappears, leaving hours of behavioral vacuum that manifests as feather plucking, screaming, and stereotypies. Foraging enrichment is not an optional extra but a fundamental welfare necessity for companion birds - matching their behavioral ecology is the foundation of adequate care.
