Abstract: By using line- and point-sampling methods, bird surveys were conducted at Guyuan County, Hebei Province in June and July of each year from 2016 to 2019. A total of 28 401 individuals were recorded, which belong to 138 species, 40 families and 15 orders. Of them, the birds of Passeriformes were the major components of the avian community, for a total of 20 049 individuals, 66 species and 21 families; 57 species (41.30%) were summer breeders and 42 species (30.43%) were transient migrants; Eastern spot-billed duck (Anas zonorhyncha) and chestnut-eared bunting (Emberiza fucata) were the dominant species of the avian community. According to their endangered status, 1 species was under first-grade state protection, 7 species under second-grade state protection, and 108 bird species were the national protected terrestrial wild animals with important ecological, economic and scientific values in China; There were 1, 2, and 5 species listed as endangered, vulnerable and near threatened species by IUCN respectively. In different habitats, deciduous broad-leaved forest has the highest Shannon-Wiener diversity (H'=3.107); town has the highest Pielou evenness (J=0.808). According to the Sørensen similarity of bird community, herbaceous swamps have similar species composition with large lakes, but deciduous broad-leaved forests and urban habitats differed greatly; The circulating components of beta diversity in different habitats of avian community were significantly higher than the nested groups. These results suggest that deciduous broad-leaved forest, large lake and small lake have stable community structure and should be the focus of bird protection and human disturbance control.
