Abstract: To provide scientific basis for protecting wetland habitats and biodiversity in Sichuan Province, we surveyed wetland birds and habitats in Sichuan Province during December 2014 to December 〖JP2〗2018. A total of 27 survey zones (sites) were set up in the West Sichuan Plateau Area,〖JP〗 Southwest Sichuan Mountains Area, and Sichuan Basin Area. A total of 141 species of wetland birds were recorded. With 24 species that were recorded in previous documentation but were not recorded in this study, there were a total of 165 wetland bird species in Sichuan Province. The 141 species recorded in this study belong to 23 families and 11 orders, accounting for 73.33%, 65.71%, and 43.79% of the number of order, family and species of wetland birds in China, respectively. Among these species, seven species were the first grade national protected animals in China, and nine species were the second grade national protected animals, 19 species were the provincial protected species. Three species were listed in appendix Ⅰ, and eight species were listed in appendix Ⅱ in CITES. There were 20 species of resident birds, 23 species of summer visitor birds, 41 species of winter visitor birds, 59 species of tourist birds, and one species of stray birds. Among those species, 79 species (59.57%) belonged to the Palearctic Realm component, 33 species (23.40%) to the Oriental Realm one, and other 29 species (20.57%) to the widespread one. The species number and population size were largest in the Sichuan Basin Area, followed by the West Sichuan Plateau Area. Winter birds and tourist birds were mainly found in the Sichuan Basin Area and the Southwest Sichuan Mountains Area, while summer birds were mainly found in the West Sichuan Plateau Area. Our results indicated that there were abundant species of wetland birds in Sichuan Province. However, human activities had been destroying wetlands and affected species biodiversity in wetlands. We should strengthen the protection of the habitats of wetland-birds.
