The Palm Cockatoo, also known as the Goliath Cockatoo or Great Black Cockatoo, is found in rainforests or woodlands of New Guinea and Cape York Peninsula in Queensland, Australia.
Palm Cockatoo’s have one of the largest bills of any parrot, only the Hyacinth Macaw’s is larger.
They have a unique territorial display in which the bird, typically the male, drums against a dead bough or tree with a large stick to create a loud noise that can be heard from up to 100 metres away. Occasionally, after drumming, the male strips the stick into small peices to line the nest.
The Palm Cockatoo is an ancient species and one of the few bird species known to use a tool, although the reason why they drum remains a mystery.
