Feather-destructive behavior, screaming, and aggression are common in companion parrots and reflect unmet welfare needs. Understanding causes enables more effective and humane responses.
Companion parrot behavioral problems are almost universally welfare problems — expressions of unmet needs in animals with extraordinary cognitive and social requirements. The most welfare-positive response to problem behaviors is behavioral assessment to identify unmet needs rather than punishment or suppression of the behavior. A screaming parrot needs more social contact and foraging enrichment. A feather-plucking parrot needs veterinary assessment for medical causes, social enrichment, and environmental complexity. An aggressive parrot needs consistent, positive interactions and avoidance of inadvertent reinforcement. Addressing underlying welfare deficits is both more humane and more effective than attempting to suppress behaviors. Consultation with a certified parrot behaviorist or avian veterinarian provides a structured approach to welfare-based behavioral modification.
