This race of Yellow-vented Flower-pecker ranges from Sikkim and Eastern Nepal to Assam, Manipur, Lushai Hills, Chittagong and Hill Tippera in Eastern Bengal.
It seems to be entirely a hill-breeding bird. In Assam we found it nesting from about 1,000 feet upwards in Lakhimpur and from. about 2,000 feet in the hotter ranges of Cachar and Sylhet, while in the Naga Hills it certainly occurs as high as 8,000 feet and again nearly as high in Sikkim. It breeds both in forest and in open country, but is much attracted by the vicinity of flowering Orchids, doubtless on account of the insects haunting these, and I have seen its nest actually attached to a flowering stem of a Dendrobium. There is little one can say of its nesting habits which is not equally applicable to any of the other Flower-peckers. As a rule its nest is not placed so high up in trees, more nests being built under than over 20 feet, while the birds often employ scraps of moss to decorate their nests outside. They also employ more grass or fibre in the support of the Bombax cotton-down which forms the bulk of the nest. This measures roughly about 4.1/2 inches from top to bottom by 3.1/2 or 3 inches in breadth.
The breeding season is April, May and June, a few birds laying in July. The birds are not, I think, double brooded. Both sexes incubate and both assist in building the nest.
The eggs number two or three in a clutch and are like all other Flower-peckers’ in appearance.
Sixteen eggs average 15.3 x 11.0 mm. : maxima 16.0 x 11.1 and 15.0 x 11.4 mm. ; minima 14.5 x 10.5 mm.
