Feather picking and self-mutilation in psittacine birds.
Feather-picking and self-mutilation behaviors are common in psittacine birds. These behaviors are best defined as stereotypic behaviors or obsessive compulsive disorders. There is likely a genetic predisposition for these behaviors as reflected in the overrepresentation of a number of species of psittacines. Stereotypies most often result from a high level of arousal and the inability to respond with the appropriate natural behaviors. More specifically, conflict may be induced by the absence of releasing stimuli or target objects. On a chemical level, stereotypic behavior appears to be related to an increased dopaminergic activity and an increased dopamine turnover. Feather-picking and self-mutilation patients are challenging to treat and are most likely to respond to treatment at an early stage of development. The best results are obtained by identifying and removing the cause of conflict, enhancing the environment, using appropriate drugs when indicated, and employing counter-conditioning.
