The Nepal house martin is a non-migratory swallow-family bird with blue-black upperparts and a contrasting white rump and white underparts, resembling its close relatives the Asian and common house martins. Its two subspecies breed in the Himalayas from north-western India through Nepal to Myanmar, northern Vietnam, and just into China (Wikipedia, general species account).
It occurs in river valleys and rugged wooded mountain ridges at 1,000–4,000m, nesting in colonies beneath overhangs on vertical cliffs. It feeds in flocks with other swallows, catching flies and other insects in flight, and is largely resident but may move to lower altitudes when not breeding (Wikipedia, general species account).
