Description
The Sincorá antwren weighs 8.5–11.5 g (0.30–0.41 oz). The adult male has brown upperparts. The face, throat, breast and upper belly are black bordered with white. The lower belly and vent are grey and the flanks are brown. The upperwing-coverts are black with white spots while the underwing-coverts are grey and white. The tail feathers are grey below with white tips and a black subterminal band. The bill is black and the feet are grey with yellowish soles. Adult females are paler above than the males and have a white face and underparts with heavy black streaking. The rusty-backed antwren (F. rufa) is similar to the Sincorá antwren but has paler and more rufous upperparts, yellowish flanks and entirely white underwing-coverts. The bird has several calls. The alarm call typically consists of three notes, a single note followed by two short notes. Other related antwrens usually have a two-note alarm call. The song is a series of repeated short notes uttered at a rate of about 2.1 notes per second, much slower than the song of the rusty-backed antwren. Pairs have a distinctive short duetting call, often given after singing. Birds also give a soft whistling distress call and a harsh scolding call.
