“…Subordinate Japanese macaque females have been reported to emit greeting calls often at dominant adult females (Mori ; Blount ; Shizawa ); however, this was not the case with our study (prediction 2‐2). More data are needed to determine whether this result is due to insufficient data or the effects of between‐group differences of social relationships (e.g., tolerant tendencies; Koyama et al.…”

“…), and some other primate species. Shizawa () reported that Japanese macaques use ‘short low coos’ in addition to grunts and girneys, before grooming interactions. Short low coos have almost the same acoustic characteristics as ‘coo calls’ (Sugiura ) but are of low‐amplitude and shorter than 0.2 s (Green ).…”

“…These calls are termed 'grunts' and 'girneys' in macaques (Macaca spp., Silk et al 2000;Whitham et al 2007), baboons (Papio spp., Cheney et al 1995), and some other primate species. Shizawa (2001) reported that Japanese macaques use 'short low coos' in addition to grunts and girneys, before grooming interactions.

“…Females also emit greeting calls toward the infants of other females (Bauers 1993;Whitham et al 2007;Frank & Silk 2009), or as signals of reconciliation (Cheney et al 1995;Silk et al 1996). Greeting calls are frequently uttered by subordinate females to dominant females, or between unrelated females (Mori 1975;Blount 1985;Shizawa 2001).

Development in the Usage and Comprehension of Greeting Calls in a Free‐Ranging Group of Japanese Macaques (Macaca fuscata)

The main objective of this study is to clarify the developmental process involved in both the usage of greeting calls and the response to greeting calls by Japanese macaques. These greeting calls facilitate affiliative interactions by communicating benign intent. Specifically, individuals frequently emit greeting calls when interacting with less‐predictable individuals. Here, we examined whether the targets at which greeting calls are directed, along with associated behavioral responses, differed among the age classes, by conducting a cross‐sectional observation of females aged 0–5 yr and their mothers. We found that infant females showed a weak tendency to emit greeting calls at no specific receivers, unlike that by older females. Adult females emitted greeting calls more frequently when approaching unrelated females than related females. In contrast, young adult or juvenile females exhibited no significant difference in the proportion of the calls with related and unrelated conspecifics. Adult and young adult females were more likely to respond affiliatively to other individuals that approached using greeting calls compared with silent approaches, whereas juveniles did not exhibit different responses to the two types of approaches. This study showed that the target‐specific usage and affiliative response to greeting calls emerge with changes in the developmental stage. Furthermore, the fact that even young adults did not use greeting calls as adults indicates that the usage of greeting calls is modified in conjunction with the expansion of social relationships.
