Baikal teal  (Anas formosa)

The Baikal teal breeds in eastern Siberia, Russia, and journeys through Mongolia and North Korea to winter in Japan, South Korea and mainland China. In winter it is also occasionally seen in Taiwan and Hong Kong (2), and there have been 70 records of this duck as a vagrant in Europe (6).

During the breeding season the Baikal teal nests in open tussock meadows close to water, as well as in mossy bogs with stands of willows (Salix spp.) and larch (Larix spp.). Over winter, it can be found on freshwater lakes, rivers and reservoirs at night, and feeding on farmland through the day (2).
