Abstract:Estimated at less than 1000 individuals, the Baer’s Pochard (Aythya baeri) is a critically endangered (CR) species, and has been receiving widely attention in the world. China is one of the main distribution ranges for this species, here we summarized the distribution of Baer’s Pochard in Shaanxi Province based on field observations. The bird was found at Yanming Lake in Chanba Ecological Reserve of Xi’an City, Panzhuang village in Hancheng City, National Nature Reserve of Hongjiannao in Yulin, Dongfeng reservoir in Fengxiang County, Tianji Lake in Weiyang District Xi'an City, Luofu Lake in Huayin City Shaanxi Province and Qianweizhihui Wetland in Baoji City, Shaanxi Province from 2017 to 2021 (Table 1). The results showed that the distribution of Baer’s Pochard was only in the Weihe River basin to the north of Qinling Mountains, the wetlands in the middle reaches of the Yellow River and Yulin Great Wall sandstorm area in the North of Shaanxi Province. The Baer’s Pochard was first found of breeding at Liujiahaizi in Yulin.
