White forepart of head and large patch on fore-neck are diagnostic of the species, rest of head and neck black. Otherwise they are brown above with black wings, rump and tail; lower neck and chest rich rufous chestnut becoming black on center of under parts. The sides and flanks narrowly barred black and white. A high, reedy whistle, "tsree-tsree-tsreeo," quickly vocalized, is often repeated in flight.
