Willie Wagtail

The willie (or willy) wagtail (Rhipidura leucophrys) is a passerine bird native to Australia, New Guinea, the Solomon Islands, the Bismarck Archipelago, and Eastern Indonesia. It is the largest, and most well-known, of the Australian fantails.
The willie wagtail is contrastingly coloured with almost entirely black upperparts and white underparts; the male and female have similar plumage.
Very common bird in gardens, parks, in fact everywhere except dense forest.
