Parrots and other companion birds evolved to spend hours daily foraging for food. Providing food in bowls without foraging challenge causes behavioral disorders from psychological frustration.
Foraging deprivation is among the most significant welfare harms experienced by companion parrots and is almost universal in the kept parrot population. The psychological need to search and work for food is a fundamental motivation - birds who cannot express it develop the avian equivalent of obsessive-compulsive behaviors. Feather-destructive behavior, once established, is extremely difficult to eliminate even when foraging is subsequently provided. Prevention requires implementing foraging enrichment from the earliest stage of bird ownership. The good news is that foraging enrichment is inexpensive and can be created from commonly available materials - the barrier is owner knowledge rather than economics. A parrot that forages for 2-4 hours daily shows dramatically different behavior than one that eats from a bowl in 10 minutes.
