The Restless Flycatcher 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. Young birds are duller grey black above, with the throat and breast washed orange-brown. The slightly smaller northern Australian sub-species,nana, known as the Paperbark Flycatcher, has a smaller bill and has the glossy blue-black colouring extending further down the back. The Restless Flycatcher is an extremely mobile and active bird and is able to hover while feeding, uttering a grinding call that gives it yet another common name: Scissors Grinder.
