Gould, P.Z.S., 1837, p. 145. Type, Oreocincla novae-hollandiae (=lunulata).
In the genus Oreocincla the sexes are alike; the under wing-coverts and axillaries are each of two colours, those on the axillaries being transposed or reversed on the under wing-coverts; the lower plumage is spotted or marked with straight or somewhat crescentic bars; the rictal bristles are few and confined to the gape. The tail is short and the under tail-coverts ample. There is a distinct colour-pattern in the underside of the wing.
The majority of the members of this genus are sedentary but aurea is migratory with resident geographical races.
The bill varies very greatly in size and shape, in some being small and shaped much as in Turdus, whilst in some, as in O. imbricata and O. nilgirienris, it is very long and heavy, very like the bill in the Thrushes of the genus Zoothera.
