geographic races have been described. They also occur in New Guinea and on many islands such as Aru, Waigeo and Misool.
Cockatoos are popular pets. They can live for many decades and are often included in wills. They can no longer be exported from Australia but many make the northern pet trade through illegal exports from adjacent non-Australian territories and breeding by aviculturalists. They attract handsome prices outside Australia.
Cockatoos have a very loud, raucous call-probably a protective "strategy" that puts off potential predators. They cause mega-damage to fruits and nuts and farmers are allowed to shoot pesky individuals.
A Sad Note
Psittacine Beak and Feather Disease. This is a viral disease that is usually fatal. Some birds have an immunity to the ailment. It manifests itself in several ways. The bird's dander, the powdery coating on the feathers, is destroyed and the birds lose the ability to keep the feathers clean. So they always appear dirty. The feathers are affected. The shafts seem to not allow the feathers to open. There is feather drop and the topnotch is often lost. Birds acquire the infection in the nest and if they develop more or less normally, they eventually suffer diarrhea, vomiting and loss of appetite.
One of the sadder aspects of the disease is that the beak is often affected and can even fall off. When this happens, the bird's ability to feed is greatly limited.
Many parrot species can be affected by PBFD and it is disappointing to see a pet develop the symptoms and have to be euthanised.
