Feather destructive behavior in companion parrots is a major welfare indicator, often reflecting chronic psychological distress from inadequate social and environmental conditions.
Feather destruction in parrots — including plucking, barbering, and self-mutilation — signals significant psychological suffering. It often develops in birds kept alone, in small cages, or without sufficient cognitive challenge. Once established, it is difficult to reverse and indicates the animal has been chronically under-stimulated or socially deprived.
