The head has a dark brown crown, a long, wide pale yellow supercilium, a blackish patch behind the eye and grey sides to the neck. The underparts are ochre yellow, strongly buff on the flanks and greyish on the lower belly, with rich chestnut streaks on the breast sides and flanks. (Wikipedia, general species account)

This small passerine breeds in northern Russia from the Ural Mountains eastwards across Siberia, typically in subarctic deciduous forests and open coniferous woodland, often close to water, though it also occurs in mountains and spruce taiga. It is migratory, wintering in Korea and eastern China, and in winter it uses bushes and shrubs, frequently near streams, but may also be found in dry grassland and woods. It is a rare visitor to western Europe and northwestern North America. (Wikipedia, general species account)
