In the winter of 2013,authors surveyed waterbirds at the north shore of Yellow River in Jinan. On the November 30th and December 4rd ,7th , we found 3 ducks were very different from others in the same water area(36°74′29.0″N， 116°98′41.3″E， 19m above sea level) in the Reservior of Queshan, they were swimming with Little Grebe(Tachybaptus ruficollis), Green-winged Teal(Anas crecca), Great Crested Grebe(Podiceps cristatus), Smew(Tadorna ferruginea), Goosander (Mergus merganse) or along, while diving to feed. How long they diving were longer than other ducks. With the help of canon 7D witch EF100-400MM lens, we took pictures for them which were lagely white; bread, back dark brown; scapulars pearl gray; stubby bill shows pink band; long tail is conspicuous in flight.
