The brown-winged schiffornis is 15.5 to 16.5 cm (6.1 to 6.5 in) long and weighs about 22 to 38 g (0.78 to 1.3 oz). The sexes have the same plumage. Adults of the nominate subspecies S. t. turdina have an indistinct pale ring around the eye on an otherwise brownish olive face. Their upperparts and tail are dull brownish olive. Their wings are dull brownish olive with rufescent feather edges. Their breast is a lighter brownish olive-gray and their belly and vent pale olive-gray. The other subspecies of the brown-winged schiffornis differ from the nominate and each other thus: S. t. Voice: The brown-winged schiffornis' song is a variable "sequence of normally 2–4 clear, rich musical whistles, last one sharply upslurred". It has been written as "teeeeu, weee, tu-weeeé", "weeeeee … PREE, a-weET", and "teeuu, yoowée, tu, tu-wee". The species also makes a "short rattling chatter".
