Feather destructive behavior (FDB) affects up to 10% of captive parrots and is a visible indicator of psychological distress or physical illness that requires professional evaluation.
Feather destructive behavior is one of the most visible manifestations of psychological suffering in captive parrots. When a bird begins pulling out its own feathers, over-preening to the point of skin damage, or self-mutilating, it is signaling profound distress - whether from psychological causes like boredom and isolation, or physical causes like infection or skin irritation. The welfare implications are serious: active self-mutilation causes pain and open wounds that invite infection. FDB tends to be self-reinforcing once established, making prevention through appropriate husbandry far more important than treatment. Parrots are among the most cognitively complex animals commonly kept as pets, and their behavioral needs - foraging, social interaction, problem-solving, and novelty - are frequently inadequately met.
