Adults of the nominate subspecies O. f. fumicolor have a warm brown crown and wide whitish supercilium that begins at the lores and becomes somewhat ochraceous past the eye. The rest of their face is grayish. Their upperparts are rufescent brown that becomes a rufous brown on the rump. Their wings are dusky or blackish with two prominent rufous wing bars. Voice: The brown-backed chat-tyrant usually sings from a perch but occasionally while hidden. Its song in Venezuela is described as "as a fast, rhythmic duet, plee, plít'ter'tew, plít'ter'téw..." and in Peru as "a weak, squeaky chatter, often in duet, of tsi'wit and tee notes". Its dawn song in Ecuador is "a fast chattered keé-ke-de keé-ke-de keé-kedu-keéekeé-ke-du-keé".
