Pairs give several calls "including a soft cooing or clucking, [a] harsh ´cow´, and [a] fast, repeated ´kawuck´."

Status: The IUCN has assessed the rufous-headed chachalaca as Vulnerable. Its range is fragmented and its population small and declining. Habitat destruction and hunting are the primary threats.
