The Guianan Cock-of-the-rock is rather quiet, except within the display area (Hilty and Brown 1986). The most frequent vocalization of males, given both at and away from the lek, is described as "a loud, crowing GET-REAL, [the second] note somewhat drawn out" (Hilty 2003). Males also give a variety of "low wavering caws, gabbling, and various rough notes" during aggressive interactions (Hilty 2003). Foraging males also give, typically at long intervals, a "nasal, drawn-out qaaaOWW" (Hilty 2003).
Geographic variation in vocalizations is not reported.
The male and female of the species vocalize all year round, but primarily during mating seasons.
The Guianan Cock-of-the-rock vocalizes from day break until night during breeding seasons.
