AbstractFood transfer happens regularly in a few nonhuman primates species that are also characterized by remarkable social tolerance. Sichuan snub-nosed monkeys (Rhinopithecus roxellana), or golden monkeys, which exhibit high social tolerance in their social relationships are thus of interest to see whether tolerance would extend to food transfer. In this study, branch feeding activity was observed in a semi-captive group of Sichuan snub-nosed monkeys, which consisted of 10 subjects that included a one-male unit (OMU) and an all-male unit (AMU). We recorded 1,275 food interactions over 27 days, and 892 instances of food transfer. The most commonly observed types of food transfer behavior were co-feeding (62.1%) and relaxed claim (22.8%). Of 892 food transfers, 756 (84.8%) took place in the OMU, most of which were among adults (34.7%) and among juveniles (42.1%). The transfer success rate was high in both the cases (87.9% for adults and 78.9% for juveniles). Food transfer in the AMU took place less often than that among adults in the OMU though with similar high transfer success. Food transfer between the OMU and AMU was limited to juvenile males from the OMU and adults from the AMU. These results provide the first evidence of food transfer in golden monkeys and suggest that tolerant social relationships in golden monkeys make transfer possible.; Food transfer happens regularly in a few nonhuman primates species that are also characterized by remarkable social tolerance.
