Biodiversity monitoring on mammals and birds are of great importance to the regional biodiversity assessment. From May 2018 to June 2019, we deployed 60 camera traps in 60 1km × 1km in Miyaluo Provincial Nature Reserve, Sichuan Province, to investigate its terrestrial mammals and birds. With an extensive survey effort of 19 252 camera-days from 58 camera stations with valid data, we identified 45 wild mammal and bird species belonging to 8 orders and 20 families. There were 6 and 11 species that are listed as Class Ⅰ and Class II of national protected wildlife species, respectively. Four species were categorized as Endangered and three as Vulnerable by IUCN Red List. For mammals, Carnivora was the order with the highest species richness (10 from 6 families), followed by Artiodactyla (7 from 4 families). According to the relative abundance index (RAI), the three most abundant mammal species were Chinese serow (Capricornis milneedwardsii, RAI = 19.58), hog badger (Arctonyx collaris, RAI = 11.58) and yellow-throated marten (Martes flavigula, RAI = 5.56). For birds, the three most abundant birds were blood pheasant (Ithaginis cruentus, RAI = 9.18), chestnut thrush (Turdus rubrocanus, RAI = 3.27) and Chinese monal

(Lophophorus lhuysii, RAI = 2.91). Comparing with historical records of Miyaluo, our results added 2 mammal species and 4 avian species, including Siberian weasel (Mustela sibirica), Altai weasel (M. altaica), plain-backed thrush (Zoothera mollissima), scaly thrush (Z. dauma), white-browed bush robin (Tarsiger indicus) and grey-headed woodpecker (Picus canus). Our data constructed the base of local biodiversity information for both community structure and relative abundance. The results will provide key basic information and support for the regional biodiversity assessment and conservation planning of the nature reserve network in central Qionglai Mountains.
