Black-bellied Antwren Formicivora melanogaster

Small antbird with a long tail and distinctive plumage. The male is dark gray brown above and black below with an obvious white eyebrow, white wing bars, and a white-tipped tail. The female is brown above with a whitish throat and buff below. Found in the understory of deciduous forests and caatinga scrub where it occasionally follows mixed-species flocks. The song is a repetition of nasal “tjew” notes.
