Paperbark Flycatcher

This is the smaller northern Australian sub-species, nana, which has a smaller bill and has the glossy blue-black colouring extending further down the back than the Restless Flycatcher.

It has a glossy blue-black head, with a small crest, and is white below, from the chin to the undertail, with a blue-black bill surrounded by bristles.
The back, wings and tail are darker grey and there may be a slight orange brown tint on the breast.
