The falcated duck or falcated teal (Mareca falcata) is a gadwall-sized dabbling duck from the east Palearctic (East Siberia and Mongolia to North Japan; wintering to India). The falcated duck breeds in eastern Asia. It nests in eastern Russia, in Khabarovsk, Primorskiy, Amur, Chita, Buryatia, Irkutsk, Tuva, eastern Krasnoyarsk, south central Sakha, Sakhalin, extreme northeastern North Korea and northern China, in northeastern Inner Mongolia, and northern Heilongjiang, and in northern Japan, Hokkaidō, Aomori, and the Kuril Islands. It is widely recorded well outside its normal range, but the popularity of this beautiful duck in captivity clouds the origins of these extralimital birds. This dabbling duck is strongly migratory and winters in much of Southeast Asia. In India: Uttar Pradesh, Bihār, Assam, eastern Haryāna. Also in northern Bangladesh, northern and central Myanmar, northern Laos to the Mekong River, northern Vietnam (from about Hanoi north), and China: Hainan, Taiwan, Yunnan, Guangxi, Guangdong, Fujian, Jiangxi, northern Hunan, Hubei, Zhejiang, Anhui, Jiangsu, Shandong, southern Hebei, Shanxi, northern Shaanxi. It is gregarious outside the breeding season and will then form large flocks. It is estimated that there are about 89,000 falcated ducks in total; this is much higher than the previous population estimate of 35,000 worldwide. During a survey done in Central China, a migratory area in the winter for the falcated duck, the numbers of animals sighted was minimal. In 2004 only 4 were recorded, and in 2005 only 10. This is a species of lowland wetlands, such as water meadows or lakes, and usually feeds by dabbling for plant food or grazing. The National Nature Reserves supported high proportions of eastern China's populations of globally threatened Anatidae species (IUCN, 2009): 30% of the near threatened falcated duck (Anas falcata) populations. There is about twenty-seven percent of falcated duck species existing in the National Nature Reserves.
