In this study, Mandarin Ducks spent a similar proportion of their time foraging as the Ferruginous Pochard Aythya nyroca (Muzaffar, 2004), and less than that of the Tundra Bean Goose Anser fabalis (64%) (Liu, 2011),
Swan Goose Anser cygnoides (60.2%) (Zhang, 2009), and Tundra Swan (30.52%) (Shao et al., 2018).
