Palm cockatoos, or Probosciger aterrimus, are set apart from other cockatoos, and the cockatiel, due to their striking appearance. They have loud calls, which have been said to sound like the braying of a donkey, when heard from a distance. 


Palm cockatoos have an almost entirely black plumage, with some grey. They also have a black beak, but their cheek contours are a bright red. As with all cockatoos they have a head crest.


Thanks to their powerful bills, these birds can crack open and eat thick shelled nuts. These form a large part of their diet, but they also eat fruit and seeds.


During nesting period, the males have been known the bang a stick against a tree stump. They nest in hollow trees, and, strangely for cockatoos, they line their nests with sticks. They lay 1 white egg.


Palm cockatoos are found throughout New Guinea, excluding the central region. They are also found in northern Papuan and Cape York.
