Какатоїс-голіаф Probosciger aterrimus

Distinctive dark cockatoo with truly massive bill. Inhabits rainforests and woodlands of New Guinea and northern Cape York Peninsula. Large patch of bare red skin on the cheeks and a long black crest distinctive. Use sticks to "drum" on trees during territorial displays. In flight, note all-black tail (Red-tailed Black-Cockatoo has bright red tail panels). Voice a sharp whistle or squeak, lacking the mournful, drawn-out wailing quality of Red-tailed Black-Cockatoo.
