Vocalizations

The song of male Swallow-tailed Nightjar is described as "unmistakable and beautiful ... a vibrating worr-r-r-e-e-e-e-e-r, at first sliding up, then dropping down" (Ridgely and Greenfield 2001b) and as "a rough growl, rising in pitch and volume, then abruptly falling: wuuurrrRRRREEEEEEERrrrrrrrby" (Lane, in Schulenberg et al 2010). The song is similar to the song of Wattled Guan (Aburria aburri) (Ridgely and Greenfield 2001b), though weaker with a little less variation in pitch. The song is delivered from the ground.

Other vocalizations include "a liquid, rising pwip, and a musical mellow stuttered whistle when agitated" (Lane, in Schulenberg et al. 2010).

Additional aurio recordings of vocalizations of Swallow-tailed Nightjar can be heard at Macaulay Library and at xeno-canto.
