Abstract:Chinese merganser (Mergus squamatus) is a globally endangered species. Population monitoring of this species was carried out in Tianmu River during the period of 2015-2018. A total of 106 individuals belonging to 25 groups were repeatedly observed. The average number of each group was 4.24±0.98, and the sex ratio was 1:3.82. These mergansers mainly integrated 3-6 individuals per group and were divided into 3 groups, namely the parthenogenetic group, female group and mixed group. Mergansers mainly inhabited open river with river width of 30-60 m and a sandbar near. The depth of the shallow water is normally 40-60 cm with the flow rate of 0.3-0.5 m·s-1. Mergansers were sensitive to human activities, because their habitats were far away from the human residential areas (within 30 m from the highway) and isolated by dense tree, shrubs or bamboo forest.
