Brown-backed Chat-Tyrant

The brown-backed chat-tyrant is 14.5 to 16 cm (5.7 to 6.3 in) long and weighs 16 to 19 g (0.56 to 0.67 oz). The sexes have much the same plumage though females have somewhat paler and duller underparts than males. 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".
