Appearance:

Falcon or cuckoo-like, nocturnal bird with long tail and slender, pointed wings. Unmistakable when seen in areas where no other species of nightjars occur, or when singing. Hard to distinguish from Red-necked Nightjar in the field, but smaller size, smaller head compared to body and shorter tail give indications. If plumage is seen clearly, note general tone (grey brown), dark front edge of arm, broader upper wing-bar and small white throat patch.

Sound:

Song unique among birds, but quite similar to Mole cricket. A mechanical, continuous slur, like the sound of a distant motorbike. As opposed to the Mole Cricket, it often "shifts gear" by changing pitch to a note approximately a fourth below the drone. Flight call a peculiar "kew-eek", with a nasal and frog-like timbre.

Appearance:

Unmistakable in breeding plumage with golden, speckled upperparts and white-bordered black throat and belly. Male generally blacker than female, but due to regional differences, some females may be darker than males from other areas. Juveniles and birds in winter plumage, lacks the black underparts, and could be mistaken for Grey Plover. Differs from that species in more golden coloured back, less heavy bill and neck and by being slightly smaller. In flight easily told apart from Grey Plover, Pacific Golden Plover and American Golden Plover by white axillaries.

Sound:

Most common call at breeding ground a disyllabic, melancholic and wailing whistle with the end falling in pitch. In song flight also a trilling, warbling and cyclic "preecaria-preecaria-preecaria". Contact call a straight, short "kluee".
