The Little Himalayan Martin, Jerd.
Coloration. Rump white, the feathers delicately fringed with black; with this exception the whole upper plumage is glossy bluish black; wings and tail dull black, some of the coverts margined and tipped with glossy bluish black; lores and sides of the head deep black with a very slight gloss'; chin and throat black speckled with white; fore neck, breast, abdomen, vent, and legs white ; under tail-coverts, axillaries, and under wing-coverts deep black.
Some birds, probably the young, have the point of the chin black, the remainder of the chin and the whole throat white ; and in these birds the underparts are not quite so pure a white as in those with black throats.
Bill brown, paler at gape ; legs and toes fleshy white.
Length about 4.5; tail 1.8; wing 3.7; tarsus .45; bill from gape .4; tail quite square at tip.
Distribution. The Himalayas from Naini Tal to the Daphla hills in Assam, and thence southwards through the hill-ranges to Manipur. This Martin appears to ascend the Himalayas up to at least 8000 feet, and it also appears to be found on those mountains throughout the year, as I have seen specimens procured in Sikhim in every month from June to January. It probably visits the lower valleys and plains in the winter months only.
