A medium-sized, long-tailed bird of lowland forest thickets, often near streams. All over sooty-gray plumage, with a short white eye-brow, white throat and a black chest with white dots. Likes to stay in cover, where it often twitches and fans its tail. Similar to Black and White-bellied Thicket-Fantails but Sooty has a black belly, and lacks the white wing bars and white tips to the tail. More often heard than seen. Most commonly given call is three explosive, downslurred notes “tyu-tyu-tyu!”.
