Sounds and Vocal Behavior

Vocalizations

Flight calls of Least Nighthawk are described as a low churr and a weak nasal beep or week" (Hilty and Brown 1986, Hilty 2003) or as "a short, sharp whit or bit, often repeated in quick succession, e.g., whit whit whit whit" (Cleere 1998). The song, which is given while the bird is perched on the ground or in a bush, is described as "a fast cur-cur-cur-curry (or chu-chu-chu-chu-chuEE)", often repeated rapidly in succession (Hilty 2003), or as "a rapid series of 5-10 resonant notes k-k-k-k-k-kurree, the last note rising in pitch at the end" (Cleere 1998).
