It has a white supercilium, throat, and foreneck. Its back, rump, wings, and tail are bright cinnamon-rufous to rufous-chestnut. The tips of its outermost primaries are dark brown. Voice: The long-billed woodcreeper sings during the day, but infrequently. Its song is a "oud and far-carrying...series of 3-4 eerie and plaintive whistles, e.e. 't w o o o o o ó o o...t w o o o o o ó o o'." It is also described as "loud melancholy-sounding, drawn-out calls 'wuuuueet' " repeated three or four times.
