The Siberian Thrush (Zoothera sibirica) is a member of the Thrush family Turdidae.
It breeds in taiga in Siberia. It is strongly migratory, with most birds moving to southeastern Asia during the winter. It is a very rare vagrant to western Europe. It is very secretive.
The Siberian Thrush is similar in size to the Song Thrush. It is omnivorous, eating a wide range of insects, earthworms and berries.
The male Siberian Thrush is a dark blue-grey above and below, with a white stripe above the eye. The lower belly and flanks are white. The female is a much browner bird, with a buff stripe above the eye.
A striking identification feature of both sexes in flight is the black band on the white underwings, a feature shared with the Scaly Thrush.
