Asian thrush

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 no doubt will be generically reassigned at some point.

Taxonomy
Based on Alström et al. (2016), the Plain-backed Thrush, Zoothera mollissima, has been split into:


 * Alpine Thrush, Zoothera mollissima
 * Himalayan Thrush, Zoothera salimalii
 * Sichuan Thrush, Zoothera griseiceps

There is possibly a fourth species, "Yunnan Thrush", but more work is needed.
