A dark, medium-sized nightjar with a somewhat long tail and wings. The crown and back are markedly paler gray, and the white throat patch can sometimes be hidden. In flight, note the white patch on the outermost flight feathers. Found in open woodland, forest clearings, and mangroves. The song consists of 4-5 loud, hard notes delivered in a level series: “chowk-chowk-chowk-...”.
