8 typical green spaces in parks in the main urban area of Wuhan City were used to study the relationship between the characteristics of parks in urban and the diversity of birds.Records of observing birds from 2022 to 2024 were obtained by combining the data from the China Bird Watching Record Center with field surveys including direct on-site counting and song surveys.The data on the types of bird habitat， ecological groups， type of resident， and endangered and rare species in the green spaces in parks in the urban built environment were analyzed.The results showed that 251 species of birds belonging to 58 families and 18 orders were recorded.The composition of species was dominated by Passeriformes， with resident birds and winter migratory birds as the main type of resident， and songbirds as the main ecological group in each park.Rare and very rare species were mostly distributed in large areas of forests and wetlands in parks with less interference from human.There were more species of birds distributed in parks with natural vegetation.The richer the types of habitats and the more complex the structure of vegetation， the greater the effect on the diversity of birds.The unique type of habitat in the Hankou Riverside Park and Wuhan Botanical Garden significantly promoted the diversity of birds and had strong appeal to rare species of birds.The diversity of birds was positively correlated with the area of green space in parks， the coverage of vegetation， the structure of community， and the degree of naturalization in the surrounding areas.Among these factors， the structure of community had the most significant effect on the diversity of birds.It is indicated that improving the diversity of habitats， increasing the use of indigenous plants， and enriching the structure of plant community in urban green spaces are of great positive significance for increasing the diversity of birds.
