Outline of Final Research Achievements

I observed Assamese macaques (Macaca assamensis) at Shivapuri Nagarjun National Park and other areas in Nepal. Like other macaques, the Assamese macaques in this area formed a multi-male multi female group with male dispersal. Males showed mounting and hugging behavior with another male, and sometimes held an infant in their social group. Unlike Assamese macaques in Thailand and Tibetan macaques (M. thibetana), however, Assamese macaques in Nepal did not show penis sucking and bridging behavior (two adults lift an infant together).
