     Female calls are loud and distinctive during mating, especially in the primates. It may be relevant to female mating strategies. Female Taiwanese macaques (Macaca cyclopis) make calls during mating, but the pattern of copulation calls hasn’t been clearly reported. Therefore, we were aimed to investigate copulation calls of female Taiwanese macaques, and to examine how the calls associated with their mating activities. This study was conducted on habituated and provisioned groups in southern Taiwan, over which mating activities of 20 identified adult females were observed by focal animal sampling. During each focal sample, mating activities of the focal animal were recorded for who initiate mounting, whether males ejaculate, the mounting series, and whether and when females call during the mating activity. In the mating season from October 2016 to February 2017, we observed the monkeys for about 500 hours and recorded 315 mating events, including 257 single-mounting and 58 multi-mounting series. Female copulation calls occurred in 50.7% of the mounting events. Copulations were mostly initiated by males (94.0%). Females called more frequently after dismounting (post-copulation calls, 67.5%), and they made calls more frequently if ejaculation occurred (x2=58.39, p<0.0001). Furthermore, females called more frequently during mounting when ejaculation occurred (with ejaculation:57.5% vs. w/out ejaculation:5.8%, Fisher exact test, p<0.001). The results show that female Taiwanese macaques make post-copulation calls and these calls are highly associated with ejaculation.
