It’s “What Animal am I?” Wednesday!

This structure was made by a very noisy animal whose calls have been said to sound like ‘tobacco’, ‘four o’clock’ or a sharp ‘owk owk’. It is the female who builds this structure from bark and grass, binding it with spider webs. Can you see other things that have been built into this one? The animal that made this object has a distinctive bald black head. It is silver-coloured around the throat and upper breast, with a plain, dull brown back, rump and tail, and a pale grey underbody. The eyes are ruby red. This animal lives in open forests, woodlands and urban environments in Eastern Australia. Can you guess what this object is, and who made it?
