Шиферная муравьеловка Myrmelastes schistaceus

Medium-sized antbird. Males are gray with small white spots on the wings, and females are cinnamon with pale spots on the wings. Usually found foraging in the understory or on the ground of upland forest, usually apart from mixed-species flocks. The song is a descending series of melodic notes. Males are very similar to those of Spot-winged Antbird; the two species are best distinguished by song or by female plumage: Spot-winged females have gray cheeks.
