Feather destructive behavior affects up to 10% of captive parrots and is a clinical indicator of severe psychological distress.
Parrots engaging in feather destructive behavior are experiencing significant psychological suffering. The behavior itself may cause additional pain through skin irritation and self-injury. Unlike most behavioral problems that can be addressed through training, feather destructive behavior is often a chronic condition indicating fundamental inadequacy of the captive environment for a highly intelligent social animal.
