Свинцовый колючник Thamnophilus schistaceus

Even-colored antshrike of forest under- and midstory. Often travels with mixed-species flocks. Males are plain gray; females are tawny with olive underparts. Females have a more contrasting reddish cap than other female antshrikes. Heard more often than seen; listen for a series of accelerating “awh” notes terminating in a punctuated down-slurred note.
