I have not been able to examine a young bird, but it will prove, without doubt, to be spotted.
Bill black in the dry skin; legs and feet brown.
Length about 5.5; tail 2.3 ; wing 3.2 ; tarsus 1; bill from gape .6.
Distribution. Sikhim and the Khasi hills. In the former tract this species is a resident, probably moving vertically according to season. This bird is figured by Hodgson, and there are likewise some specimens collected by him in the British Museum, probably from Nepal, but there is no certainty on this point.
