I can't help feeling sorry for that bird. It's one thing to see Galahs and SCs as pets and kept in cages, but those are both extremely plentiful species in the wild. Palm Cockatoos are not. They're at risk because of habitat reduction and they've never been common, as the part of Australia they live in is in our smallest ecosystem. Not only that, but the highly complex social structure they maintain is pretty much unique among cockatoos and not very well understood. Yet. This bird, kept in a glass box and singing for its supper, ought not to be there. He ought to be at the top of a tree-hole somewhere in northern Queensland, banging a stick on a branch to call his mate. There's a video somewhere on YouTube called 'Australia: Land of Parrots'. Check it out some time to see what real Palm Cockatoos are like.
