Siberian accentor [SEP] Distribution and habitat
The Siberian accentor breeds in a belt across northern Russia east from just west of the Ural Mountains to the Pacific coast, with a second, more fragmented, band across southern Siberia. It is migratory, wintering in east China and Korea. This species winters in small numbers in Mongolia, but only rarely in Japan. The breeding habitat is subarctic willow and birch forests, and open coniferous woodland, often close to rivers or bogs, although pairs are also found in mountains and spruce taiga. In winter, the Siberian accentor occupies bushes and shrubs, often near streams, but may also be found in dry grassland and woods.
