There are currently 106 endemic bird species listed belonging to 55 genera, 15 families and 7 orders, accounting for about 8% of China’s avifauna, of which 77 species are only found in China. Ten endemic genera are currently recognized including Nipponia, Tetraophasis, Chrysolophus, Crossoptilon, Ithaginis, Pseudopodoces, Rhopophilus, Kozlowia, Urocynchramus and Latoucheornis. The 2-dimensional distribution pattern shows that 61 species are found in Sichuan Province, 45 species in Gansu Province, 41 species in Yunnan Province and 36 species in Tibet, with much fewer species in other provinces and only 3 species in Jilin Prov. In terms of recognized zoo-geographical sub-regions, 68 species are distributed in the“ South-West Mountainous Subregion”, 58 species in the“ Western Mountainous Plateau Subregion ”and 56 species in the“ Qinghai-South Tibet Subregion” with much fewer species in other Subregions, and only 3 species in the “ Tianshan Hilly Subregion” and 1 species in the “Daxingan Mt. Subregion”. Three centers of endemism were identified by overlapping distribution maps, namely the“ Hengduanshan Mountain areas ”, “Mountain areas in north Sichuan Province and Qinling as well as south Gansu Province”, and“Taiwan Island” . These are mainly comprised of three habitat types:“High Mountain and Plateau”, “Himalayan-Hengduanshan Mt .”and“ Island” .
