Sounds and Vocal Behavior

Vocalizations

Vocal array

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).

Nonvocal Sounds

Two types of mechanical sounds are produced by the male: a loud snapping noise, from snapping the bill closed (Gilliard 1962); and a "whinnying whistle" (Gilliard 1962) or a "strident whistle" (Sick 1984), produced by the wings in flight, especially when taking flight or upon landing (Sick 1984).
