The gray matter: Prevention and reduction of abnormal behavior in companion gray parrots (Psittacus erithacus)

Gray parrots (Psittacus erithacus) are popular companion birds, particularly noted for their ability to mimic human speech, their intelligence, and longevity. They are also prone to developing abnormal behaviors such as feather damaging behavior. This review explores the current available knowledge on gray parrots kept as companion birds with respect to behavioral problems and their management. The potential causes for the development of abnormal behaviors in this species are explored. Recommendations are made for future research, and advice is provided on the synthesis and application of available research to owners, breeders, and clinicians of gray parrots so that their well-being is maximized in captivity.
