The Australian King Parrot is a large distinctive, broad-tailed parrot found in gardens, farmland, forest and woodlands of most sorts, especially if damp.
The male has a plain scarlet head and body with dark green wings, a dark blue rump and distinctive long bluish-black tail. The female is predominantly green with a scarlet belly and undertail coverts.
My younger brother feeds them regularly on his small farm located past the Dandenong Ranges (overlooking the outer eastern suburbs of Melbourne), so it was pretty easy to get some photos.
Here’s a couple more shots from Melbourne Zoo.
