Abstract

Little information exists on the types of vocalizations produced by Tibetan macaques (Macaca thibetana). Data were collected on the vocalizations of a group of 41 provisioned Tibetan macaques of both sexes and all ages at a tourist site at Mt. Huangshan, China, over two months in 2013. This allowed for the first construction of a vocal repertoire ethogram for the species, including descriptions of all observed vocalizations, the contexts in which they occurred, their production by members of each age/sex class, and their apparent intended recipients. Most vocalizations are produced by individuals of multiple age/sex classes and occur in several contexts, and the differential production of vocalizations by age classes indicates that vocalization behavior changes as Tibetan macaques develop. Similar developmental changes in vocalizations have also been documented in other macaque species.
