The Palm Cockatoo, also known as Goliath Cockatoo (sometimes applied only to the Goliath subspecies) comes from northern Australia and New Guinea.
Despite the name Goliath, it is not the biggest species of cockatoo. However, it is large, mainly black and impressive, particularly with its crest raised. It has a distinctive bare, red face patch.
It has the largest beak of any parrot except the Hyacinth Macaw. It is also one of the few birds, or indeed animals, to use tools -- it breaks off a large twig with its huge beak to use as a DRUMSTICK.
It then drums with the drumstick against a tree trunk or branch to attract a mate (Ringo would have been a great hit with hen Palm Cockatoos).
Its face becomes a darker red and its crest and cheek feathers rise as it becomes excited or agitated.
This Palm Cockatoo takes an interest in photography.

The pink and black tongue
Those immediately above look as if they have a repair on the beak; they are juveniles. The chicks have horn-coloured beaks which gradually become fully black by adulthood.
Wood whittling is a favourite pastime of Palm Cockatoos, not only to make drumsticks but to fashion other items including the bow and arrows (above)
