The diversity and impact factor of wintering waterbirds in Zhangdu Lake were investigated from January 2018 to January 2020. A total of 43 waterbird species belonging to nine families and seven orders were observed by the partition direct counting methods and the fixed-point observation. The number of species and individuals varied between years. However, Anatidae was always the family contains the largest number of species each year, followed by Ardeidae, and the absolute dominant species was Larus ridibundus. We also summarized three factors affecting the waterbird diversity in Zhangdu Lake, including the high water level due to the artificial water storage in the winter, the patchy habitat of wetland caused by the lack of hydrological connection between the fish pond and the lake water system, and the conflict between people and birds.
