Parrots in zoos and sanctuaries have extraordinary cognitive needs that conventional zoo exhibits often fail to meet, resulting in feather destructive behavior and repetitive movements.
Parrots are among the most cognitively demanding animals to house well in captivity. Their intelligence becomes a welfare liability when environments are insufficiently stimulating - they apply problem-solving capacity to self-destruction or develop complex stereotypies. Progressive parrot facilities use a 'behavioral budget' approach, designing environments so natural behavior proportions can be maintained. Many parrots in private ownership and smaller zoos live in conditions that would not meet modern welfare standards.
