Abstract
One vocalization in the Japanese macaque (Macaca fuscata) system of communication is the “girney.” Previous studies indicated that the “girney” is used for short range communication and that it tends to occur when subordinate animals approach and groom dominant ones and when females without infants approach females who have infants. Data were collected on the social behavior of adult female Japanese monkeys of the Arashiyama-A troop in Texas in order to test those results. The study indicates that “girneys” are the most frequently occurring vocalizations of females during and following the birth season and that they occur primarily in two contexts. Those are the proximity of a female to another female with a new infant and the proximity of a lower ranking animal to a higher ranking one. The contexts are ones in which the risk of aggression is high, and the “girneys” appear to function as appeasement gestures to reduce the risk.
