Gray Jays sing a “whisper song,” a series of soft melodious notes interspersed with quiet clicks, lasting up to a minute.
Gray Jays have a wide array of calls from harsh chatters to clear whistles, though they are much less vocal than other jays and crows. They can imitate the calls of their predators, including Northern Pygmy-Owls, Rough-legged Hawks, Merlins, Pine Grosbeaks, Red-tailed Hawks, Broad-winged Hawks, American Crows, and Blue Jays. This mimicry may confuse the predator or signal a threat to other Gray Jays.
Gray Jays sometimes snap their bills while chasing away intruders.
