In order to further understand the social relationships among harem females of the Sichuan snub-nosed monkeys, I conducted the study on female grooming relationships. I have studied the Sichuan snub-nosed monkeys in the Qinling Mountains since 1999. I gave name to each individual in this group, which is the first individual identification in their natural habitat. The study band was comprised of 9 one-male units in this mating season. I investigated the group composition three times a day by the scan sampling, and collected data of grooming relationships within harems by the focal sampling. In addition to the daytime observation, we collected data of nesting behavior in nights. These data will be useful in my doctoral course study and further understanding the social organizations of this species. I am grateful that the HOPE project provided me the chance to continue my field work.
