The Asian thrushes are medium-sized mostly insectivorous or omnivorous birds in the genus Zoothera of the thrush family Turdidae.Two New World species traditionally regarded as Zoothera; (varied thrush and Aztec thrush) actually belong elsewhere in the thrush family. A group containing Siberian thrush and the African species is not closely related to the other Zoothera and are now assigned to the genus Geokichla.
