Black Palm Cockatoos, as their name implies, are smoky black or grey in color. They are the largest of the Cockatoos - just as tall as a Moluccan, though they are not quite as stout. Their crest is phenomenal, having long, thin feathers that stand on end. And, unlike other Cockatoos that extend this crest only when surprised or excited, the Black Palm Cockatoo almost always has its crest on display! The area from their eyes, along their cheeks, all the way to the beak is bare skin, rather like a Macaw. But the startling thing about this is that the skin is bright red! Their tongues are black and red as well.
