Rivers and their adjacent riparian areas provide satisfactory feeding and breeding habitats for birds. As a strong indicator for the environmental health of an ecosystem, bird diversity is introduced in this study to evaluate the environmental status of CaoE River basin located in SE coastal China. Various techniques, such as remote sensing images, photography, and high-resolution video recording, are used to monitor and record the bird communities in CaoE River basin and its three main tributaries during the on-site survey period at nine different sections with 102 transects. The bird-abundance coefficient and Margalef's diversity index are both utilized in this study to show the spatial discrepancies of bird diversity from upstream to downstream of CaoE River. The variation of bird diversity at different sections are analyzed, a higher bird diversity is shown in both the upstream and downstream regions of CaoE River, whereas it is relatively lower in the central regions. Additionally, the road types, vehicle density, and field vegetation components are also accounted for in this study. It is confirmed that the development of human society and the construction of the city of Shaoxing have significant impacts on bird communities and the nearby ecosystem.
