Coloration. In general appearance similar to O. indicus. Differs in having a more slender bill; in the wing-spot or yellow on the primary-coverts being larger, the Length of the yellow marks being about three quarters of an inch; in the amount of yellow on the tail extending to nearly 2 inches on the outer feathers, and to 1 inch on those next the middle pair, against 1.5 and .4 inch respectively in O. indicus; in the narrower width of the band on the nape, which is never more than .4 inch as against .7 in O. indicus; and in the back of the male being tinged with green.

Young birds are difficult to separate. If very young, weight must be attached to the smaller bill and to the smaller amount of yellow on the tail. When the nape-band becomes indicated, however feebly, there can be no doubt to which species the bird examined belongs.

In the adult the iris is red ; bill pale pink ; inside of the mouth flesh-colour; legs plumbeous; claws dark horn-colour; in the young the bill is black.

Length about 10; tail 3.7; wing 5.9; tarsus 1; bill from gape 1.35.

Distribution. Nepal; Darjiling terai; Bhutan and Buxa Doars ; Cachar; Manipur ; Karennee ; Arrakan ; Pegu ; Tenasserim to the extreme south. Bare, but apparently a permanent resident.
