Palm cockatoos are the only cockatoo with all dark feathers. They have a backward curving erectile crest and a massive upper mandible that is larger in males than in females. The tongue is red with a black tip. The feathers have a powder down, which dulls the beak and adds a gray color to the black plumage. The legs are grayish-black with some feathers on the thighs. A red, naked facial marking is located just to the sides of the beak.
Palm cockatoos are found in rainforests, including gallery forests, forest edges, monsoon woodlands, eucalypt and paperbark woodlands, partly cleared areas, and dense savannas.
Palm cockatoos mainly eat leaf buds, seeds, and fruits. They sometimes also eat insects and their larvae.
Palm cockatoos are found in the Australasian region, including New Guinea, the Cape York Peninsula (Northern Australia), Aru Islands, West Irian, Misool Isle (Western Papuan Islands) and other islands.
IUCN red list : Least Concern (LC) (September, 2010),CITES (September, 2010)
The mating season varies with local climate, but is usually from August to January. Palm cockatoos lay one egg per clutch, which is incubated for 30 to 33 days. The newly hatched young are naked and helpless. They take 100 to 110 days to fledge, the longest period to fledging of any parrot species.
