Parrots in captivity frequently develop feather-destructive behavior, aggression, and stereotypies that reflect unmet behavioral needs and chronic stress.
Parrot behavioral disorders are predominantly welfare problems reflecting environmental and social deprivation rather than medical conditions. Feather-destructive behavior — where birds chew or pull their own feathers — is the most visible manifestation of chronic stress or frustration in captive parrots. Root causes include lack of foraging opportunities, insufficient social interaction, inability to fly freely, and absence of species-appropriate stimulation. Treatment requires addressing these root causes rather than suppressing symptoms. Parrots require significantly more behavioral investment than most companion animals, and many are relinquished when owners discover the commitment required.
