The Siberian thrush (Geokichla sibirica) is a member of the thrush family Turdidae.
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.
