Yes, Yellow-tailed Black Cockatoos do chop their way into wattle trunks
in particular - but also eucalypts and others. They are seeking
wood-boring moth and beetle grubs. They see the grub's droppings and
sawdust at the hole, and locate the grub exactly by listening for it
chewing. Then they chop a long splinter from the trunk, leaving it
hinged at the bottom, and sit on this, as if on an axeman's board, while
they mine the grub out. Clearly a skilled process. It can take half an
hour. Worth watching.
