Batara de Natterer Thamnophilus stictocephalus

Fairly small antshrike with a graduated, white-tipped tail. Males are gray overall with a black cap and a whitish center to the belly. Females have a cinnamon cap and back and are gray-buff below. Found in the lower levels of short transitional deciduous forests and white sand forests, avoiding humid forests. Sings a series of up to 20 clear notes, starting slowly and accelerating toward the end, finishing with a rattle. Very difficult to distinguish from the male of the Amazonian Antshrike, but differs in habitat. Female Amazonian Antshrike has a bright cinnamon head, not just the cap.
