Siberian Accentor

The Siberian accentor is a small passerine bird that breeds in northern Russia from the Ural Mountains eastwards across Siberia. It is migratory, wintering in Korea and eastern China, with rare occurrences in western Europe and northwestern North America. Its typical breeding habitat is subarctic deciduous forests and open coniferous woodland, often close to water, although it also occurs in mountains and spruce taiga. It inhabits bushes and shrubs in winter, frequently near streams, but may also be found in dry grassland and woods.
