                Water Birds in Lhunzhub



                Water birds come in the following species: 
                Green-Headed Ducks: 50-62 cm long, weighing 9,100-1,300 grams each, distributed in Europe, Asia, North America, Central America, and the northern part of Africa. They inhabit lakes, rivers, ponds and swamps, gathering in large groups.

                They live on leaves, buds, haulms (stems or stalks) and seeds of plants, as well as mollusks, crustaceans, water insects, small fish and shrimps. They breed from April to June with 7-11 eggs each time, which the female hatches in 24-27 days; Interestingly, the newly-born ducks can move about and hunt for food shortly after they emerge from the shells.    

                Pochards: Mainly two types, green or red-headed, belonging to the duck family, wild goose order, 42-47 cm long and weighing around 500-1,200 grams each.

                They are mainly distributed in the eastern part of Russia, North Korea, Japan, Thailand and Bengal, as well as the northeastern, northern, eastern and southern parts of China. They inhabit rivers, lakes and swamps, living as couples or in small groups, and are good at flying, diving and swimming. They live on roots, leaves and haulms (stems or stalks) and seeds of plants, as well as mollusks, crustaceans, water insects, small fish and shrimps. They breed from May to July with 6-9 eggs each time with an incubation period of 24-27 days. The young can fly after about 150 days.

                Goosanders: Mainly in two types, either common goosanders or Chinese goosanders, and the former can also be subdivided into two types as spot-headed or and red-breasted goosanders, which are said to live through the winter in Lhunzhub.

                Chinese goosanders are large in number, moving about in small groups or individually in rivers or streamlets with good quality water. There is a fistful of backward-facing feathers at the back of their heads like the caps of the officials in the Qing Dynasty, which is why they are called Chinese goosanders. They are timid and alert and avoid humans.      

                Red Sheldrake: Also called yellow duck, the female and male are identical. The male ones wear black chaplets in summer. They are similar to domestic ducks in size, but, with chestnut-colored feathers, and a yellow-colored head, they are like wild goose in appearance. They are extremely cold-resistant, distributed over the eastern and western parts of China. They are the most popular kind of migratory birds in Tibet, mainly moving about in couples or small groups.

                Black-necked Cranes: 110-120 cm long, weighing 2-3 kg each, with the female and male similar in shape. They fly from the southern part of the Qinghai-Tibet Plateau to the wetlands around lakes in the northern part to breed from late March to early April every year, flying back south to winter.

                The black-necked cranes mainly live on roots, haulms (stems or stalks) and seeds of plants, also little fish, frogs, snakes, rats and insects, and can be seen hunting for food through the winter in the harvested fields.
