Small and compact nightjar of vegetated semi-desert habitats. Overall rather pale sandy-brown, but note the distinctive rusty hind-collar and buff tips on scapulars and coverts when sitting on the ground. In flight flashes big white patches on wings and tail corners and wings appear relatively short and rounded. Also note the rich rusty underwing. Breeds under bushes, forages in open habitats, and often sits on tracks in the road. Vocalizations sound similar to a distant double-bark, "Kau-kau, kau-kau…"
