Nice footage but these are actually Calyptorhynchus funereus. Calyptorhynchus baudinii is the Long--billed Black Cockatoo found only in the South West of Westwen Australia.
Are they endangered? We get a flock each yr on our walnut tree. Ive recently read they dig in gums to eat lavae and now im wondering if they were eating the white ants in my tree or the nut.
