Abstract Background Evidence suggests that wintering waterbirds have become conspicuously more concentrated at two largest lakes of the Yangtze River Floodplain, East Dong Ting Lake (Hunan Province, 29°20′N, 113°E) and Poyang Lake (Jiangxi Province, 29°N, 116°20′E), relative to other lakes, despite the establishment of reserves elsewhere. While this relationship is likely due to greater extent of undisturbed habitats in larger lakes, we understand little of the drivers affecting individual behaviours behind this tendency. Methods We tracked wintering movements of three duck species (Eurasian Wigeon Mareca penelope, Falcated Duck M. falcata and Northern Pintail Anas acuta) using GPS transmitters, examining differences between the two largest lakes and other smaller lakes in ducks’ habitat use, duration of stay at each lake and the daily distances moved by the tagged birds while at these sites. Results The Eurasian Wigeon and Falcated Duck stayed five times longer and almost exclusively used natural habitat ...
