Striking small flycatcher with a black crest. Has a chestnut head, a black breast band, and gray underparts. Males have a black back, females an olive back. Note the yellow feather edges to the wings in both sexes. Inhabits the understory of humid forest, dense second growth, and seasonally flooded forests, favoring areas with dense vine tangles or bamboo. The song is a series of low “chewp” notes interspersed with double “chewp-chewp” notes, easily mistaken for a frog or insect.
