    Animal: Parrots, Cockatoos and Other Pet Birds

    Diagnosis: Feather-Plucking (Trichotillomania)

    Doctor's Notes: Feather-plucking, or over-preening, in birds can be attributed to many causes. Some of the issues that cause birds to pull out their feathers and self-mutilate are anxiety, over-excitement and boredom. These emotional triggers can also be seen in humans suffering with trichotillomania, also known as hair-plucking. (Pet MD)
