Тиранновая муравьянка Cercomacroides tyrannina

This skulking species lives in humid tropical lowlands, favoring thickets and tangles at forest edges and along streams. Often heard song of piping whistles usually reveals the presence of Dusky Antbirds, which usually occur in pairs but are difficult to see clearly. Male is slaty gray overall with narrow whitish wingbars. Female has a rusty “blank” face and rusty underparts.
