Серый муравьелов Myrmotherula snowi

Very rare antwren, unmistakable in its tiny range, likely now restricted to one complex of humid forest fragments in the Brazilian state of Alagoas. Males are gray with a blackish throat and females are cinnamon-colored. Forages in the understory and middle levels of the forest, usually accompanying remnant mixed-species flocks. The song is a high sharp series of whistles.
