This odd cryptic-looking bird is the only one of its family in its range. Rather like a cross between an owl and a nightjar, but note wide mouth and proportionally smaller eyes. Intricately mottled and dappled in shades of gray and brown; males are predominantly gray-brown, while females are rufous-toned. A secretive inhabitant of forests with dense understories, often roosting deep in tangles by day. Vocalizations include a horrible scratchy scream and various cooing notes, often given in series.
