Baer's pochard (Aythya baeri) is a diving duck found in eastern Asia.It is a resident bird in North and Central China, and formerly bred in southeast Russia and Northeast China, migrating in winter to southern China, Vietnam, Japan, and India.
The diving ducks, commonly called pochards or scaups, are a category of duck which feed by diving beneath the surface of the water. They are part of Anatidae, the diverse and very large family that includes ducks, geese, and swans. The diving ducks are placed in a distinct tribe in the subfamily Anatinae, the Aythyini.
This is a list of the breeds of domestic duck which have official recognition at national or international level. [1]Most breeds of duck derive from the wild mallard, Anas platyrhynchos, while a small minority are descendants of the Muscovy duck, Cairina moschata.
The male has a long pointed tail (10 to 15 cm (3.9 to 5.9 in) long) and a dark grey bill crossed by a pink band. In winter, the male has a dark cheek patch on a mainly white head and neck, a dark breast and mostly white body. In summer, the male is dark on the head, neck and back with a white cheek patch.
This is a large duck, and the male's long central tail feathers give rise to the species' English and scientific names. Both sexes have blue-grey bills and grey legs and feet. The drake is more striking, having a thin white stripe running from the back of its chocolate-coloured head down its neck to its mostly white undercarriage.
Greater scaup eat aquatic molluscs, plants, and insects, which they obtain by diving underwater to depths of 0.5–6 m, exceptionally 10 m. [4] They form large groups, called "rafts", that can number in the thousands. Their main threat is human development, although they are also preyed upon by owls, skunks, raccoons, foxes, coyotes, and humans.
