Genus GEOCICHLA

In the Thrushes of this genus the sexes are different and the under wing-coverts and axillaries are each of two colours, the position of the two colours on the under wing-coverts being transposed on the axillaries.

From Merula this genus differs in having a somewhat blunter wing and shorter tail. The underside of the wing presents a pattern formed by the white bases of many of the quills.
