The Swallow-tailed Nightjar occurs in the Andes. Males have long outer tail feathers, and the species uses forest edges and rocky walls.
It is mostly blackish with rufous spots and a collar. The male has very long outer tail feathers with white along the edge; the female has a barred, notched tail.
It favors forest edges, vertical rocky walls, and landslide edges. Records from montane forest on the eastern Andes slope are at 2,000–3,600 m.
