The Geokichla thrushes are medium-sized mostly insectivorous or omnivorous birds in the thrush family, Turdidae. They were traditionally listed in the Zoothera, but molecular phylogenetic studies published in 2008 led to their placement in a separate genus.

Taxonomy
editThe genus Geokichla was introduced in 1836 by the German naturalist Salomon Müller with Turdus citrinus Latham, 1790, the orange-headed thrush, as the type species.[2][3][4] The genus name combines the Ancient Greek geō- meaning "ground-" with kikhlē meaning "thrush.[5]
These species were formerly placed in the genus Zoothera. Molecular phylogenetic analysis by Gary Voelker and collaborators published in 2008 found that Zoothera was polyphyletic.[6][7] To create monophyletic genera 21 species were moved from Zoothera to the resurrected genus Geokichla.[8]
