Eight large urban parks in the built-up area of Wuhan were selected, and observational data from the public science platform for the three years of 2022 to 2024 were obtained. Analysis and comparison were conducted on the habitat types, bird species count, resident types, faunal composition, and endangered and rare species of birds, in order to assess the bird diversity status in Wuhan"s urban park green spaces. It was concluded that Wuhan"s urban parks play a significant role in bird diversity conservation, and the bird diversity status is positively correlated with the area of park green spaces, vegetation coverage, community structure, and the degree of naturalization around the parks. Meanwhile, a comparison was made with the bird diversity status in representative park green spaces in Beijing and Shanghai to analyze the deficiencies in the construction of bird diversity in Wuhan"s park green spaces. Based on this, measures were proposed to improve the connectivity of urban green spaces, construct large-scale woodlands in large green spaces, optimize plant configuration patterns using native species, and moderately rewild urban green spaces to further enhance the bird diversity in urban green spaces.
