Sounds and Vocal Behavior

Vocalizations

The song of White-tailed Nightjar is described as "a high, drawn-out spit-cheeeeuua, [the] 1st note faint, [the] last rising then falling" (Hilty and Brown 1989); as "a long high-pitched whistle, first rising, then going down in pitch at the end, introduced by a short dry note (inaudible at a distance), tk chweeeeeeea or pick, speeeeeea" (Ridgely and Gwynne 1989); as "a high, thin pt-cheeeeeeeee, the second note a long-drawn-out, rising whistle that falls slightly at end" (Stiles and Skutch 1989).

Calls of White-tailed Nightjar include "a scratchy wheer in flight" (Stiles and Skutch 1989); "a high see-see, irregularly spaced", also given in flight (ffrench 1991); a thin tic-tic, given when flushed (ffrench 1991); and a soft wut-wut-wut, given by the female as she approaches the chicks upon returning to the nest (Cleere 1998).

Audio recordings of vocalizations of White-tailed Nightjar can be heard at Macaulay Library, at xeno-canto, and at Internet Bird Collection.

Nonvocal Sounds

The flight display of male White-tailed Nightjar has not been described in detail, but apparently involves a "wing-clapping knock-knock sound", made by striking the wings together, and which then is followed by an audible wing whirr (Hilty and Brown 1986, Hilty 2003).
