Dark-sided Flycatcher

The dark-sided flycatcher is 13–14 centimetres long. The upperparts are plain, dark grey-brown apart from a pale wingbar and pale edging to the tertials. The breast and flanks carry a variable amount of streaky dark grey-brown, and a pale submoustachial stripe and dark malar stripe outline the white throat and half-collar. The centre of the lower breast and belly is white, the undertail-coverts are white with dark feather centres, the bill is short and dark, the feet are black, and the large eye has a whitish ring.
