Abstract:

This study used the renovated Wusong River bird habitat in Shanghai to explore the effectiveness of constructing small-scale habitats for wild animals in Shanghai. The diversity and seasonal dynamics of birds in the Wusong River habitat for birds were analyzed using line transect method and direct counting methods. Fifty-four bird species in 10 orders and 29 families were recorded, including 11 species of waterfowl, 38 species of finches, and one species of bird protected at national level Ⅱ. Among the various residence types of birds, 28(51.9%), 15(27.8%), 6(11.1%), and 5(9.3%) species of resident, wintering, summering, and traveling birds, respectively, were recorded. Among the various bird lineages, 23(42.6%) and 17(31.5%) were found at the Palearctic and Oriental boundaries, respectively, while 14(25.9%) species were widespread. The dominant species were the Chinese blackbird, light-vented bulbul, spotted dove, [tree] sparrow, Japanese white-eye, silky starling, yellow-throated bunting, and long-tailed shrike. There was a low population of both summer residents and travelers in the habitat. The bird diversity index was highest in autumn (migration period), followed by winter (overwintering period), spring (migration period), and summer (breeding period), whereas the evenness index was highest in autumn (migration period), followed by spring (migration period), winter (overwintering period), and summer (breeding period). The results confirmed the effectiveness of constructing small-scale habitats for wild animals in Shanghai, and recommendations for the construction and management of such habitats are proposed.
