The Palm Cockatoo has three subspecies. The first one is the P.a. atterimus , which is from Misool, Aru, and Northern Australia. The second one is called P.a. goliath , which is from the Papuan Islands, and West Irian extending out to Southeastern Papuan. This is the largest subspecies of the Palm Cockatoos. The third subspecies is P.a. stenolopus , which is from New Guinea and West Irian.
Most captive birds behave differently from wild birds.
Captive birds tend to display compulsive movements, and motions which they will continuously mimic. Territories are formed at tree top where nests occur. Palm Cockatoos, like many parrots, have the ability to learn and mimic the human voice. Cockatoos enjoy spending their days in the trees, digging up things, and foraging for fruits or whatever else they might find to eat. Palm Cockatoos are usually in pairs, but maybe found singlely or in groups of five to six.
