This is a Satin Bowerbird, seen in a typical Australian habitat, the outdoor barbecue! Its found around the SE corner of Australia, from the middle of Victoria to Southern Queensland.
There is also a sub-species found in a small patch of Queensland much further north).
The male bird has wonderful glossy blue -black metallic plumage, that can be a real pig to photograph!
The female is green with a splendid fine scaly pattern in the breast. Think set and chunky they really are good looking birds.
The male builds a bower (hence the name!) to attract a mate. Here the males show their fondness for blue items (or at least items we see as blue). The bower is decorated with found objects - fruit, flowers, berries, feathers and in this case milk bottle lids and straws!
Enjoy the birds.
