Wetlands are among the most productive ecosystems around the globe, with lots of ecological and social-economic services provided. Better understanding of the spatial distribution of biotic communities in wetlands is not only an important question in ecology but also critical for biodiversity conservation. From March 2022 to February 2023, 12 monthly surveys were conducted on 10 provincially significant wetlands in the Huaibei Plain using transect and point count methods. In this study, a two-way ANOVA was used to compare the differences in species, taxonomic, functional, and phylogenetic diversity of birds across the four seasons and the six habitats. A total of 129,916 individuals, 218 bird species belonging to 54 families and 18 orders were identified during the survey. During spring, species richness was significantly higher in rivers (55.67±4.93), shelterbelts (47.67±6.51), and gardens (44.67±5.29) compared to farmlands, lakes, and ponds. In contrast, farmland in summer exhibited greater species richness (SR) (46.67±7.00), Shannon (3.13±0.10), Pielou (0.82±0.02), and phylogenetic diversity (PD) (1431.31±129.92) than shelterbelts, gardens, and lakes. River, lake, and pond habitats showed notably higher taxonomic diversity (TD), functional diversity (FD), and phylogenetic diversity (PD) during autumn, while the highest functional diversity (FD), and phylogenetic diversity (PD) levels were observed in rivers, lakes, and ponds in winter. There were no significant differences...
