Abstract: Homosexual mounting behavior in non-human primates is very common, but its function may vary across species. We studied male-male mounting behavior in a wild troop of Tibetan macaques (Macaca thibetana) at Mt.Huangshan China, from August 2010 to May 2011. We used focal behavior sampling and continuous recording to document mounting related behaviors. We found that this behavior occurs among males of all ages, but its frequency decreases with increasing age (P<0.05). Homosexual and heterosexual mountings differ in that the former ones can have 1 or 2 steps, while the latter ones have 4 distinct behaviors. The contexts of male-male mounting varied across the male lifespan. Mounting behavior exhibited during immaturity is crucial to the development of adult homosexual mounting behaviors.
