A slender, medium-sized bird of lowland and foothill forest interior. Fairly long tail and black face with gray bill and blue eye wattle. Male has white belly and collar, black tail, back and wings with a white wing patch. Female has orange chest, throat and collar with rufous tail, back and wings. Limited overlap with the similar Ochre-collared Monarch, but Frilled male has a white rather than orange collar, and the female a rufous rather than brown back. Voice, a series of buzzing notes, sometimes interspersed with a high-pitched “whip”, and an up-and-down whistled song.
