Mt. Gaoligong, situated along the China-Myanmar borderis, is one of the biodiversity hotspots in the world. However, we have limited knowledge about the fauna diversity in this area due to complex terrain, and dense vegetation. During November 2013 to September 2015, we had investigated the biodiversity of mammals and birds by deploying 30 infrared camera traps in the west slope of mid-section of Mt. Gaoligong at Pianma, Yunnan, China. We established 41 different camera sites with 9,503 camera-trapping days and obtained 808 independent images. We identified 21 mammals and 24 birds, belonging to 10 orders, 21 families and 38 genera. We also identified Rhinopithecus strykeri, a recently discovered non-human primate species in the mid-section of Mt. Gaoligong. Primates, Carnivora, Artiodactyla, Passeriformes, Galliformes and Rodentia were the most abundant orders and widely distributed in the study area. Based on the detailed time records from seven most abundant species, the results were shown that: (1) Macaca assamensis, R. strykeriand Ithaginis cruentus had similar daily activity pattern with one peak in the morning and another in the afternoon;(2) the activity pattern of Dremomys lokriahand Myophonus caeruleus peaked at noon, but D. lokriah had another peak at dusk; and (3)Martes flavigula and Sus scrofa exhibited nocturnality, but S. scrofa were more active at night. This survey provide basic and valuable information for current status of mammal and bird diversity at Mt. Gaoligong, which are essential for wildlife monitoring and biodiversity conservation for this area.
