How captivity affects animals

[Pajarita]

This is an article meant mostly for zoo and commercially farmed animals but it is perfectly applicable to pet parrots that are in distress. The stereotypies (unusual and repetitive behaviors) are all found in parrots, sometimes exactly alike as in the case of overgrooming (over-preening, barbering, plucking) and mutilation and, sometimes, with a bit of a variation - like when they talk about elephants, wolves, lions, bears, etc pacing or walking in circles but, in parrots, it manifests in them in the constant climbing the inside of the cage. Large animals bite the bars of their cages and parrots do the same exact thing! And then with parrots we also have the screams and the aggression, of course.
