High Quality Content by WIKIPEDIA articles! The Nepal House Martin (Delichon nipalense) is a non-migratory passerine of the swallow family Hirundinidae. Its two subspecies breed in the Himalayas from northwestern India through Nepal to Burma, northern Vietnam, and just into China. It occurs in river valleys and rugged wooded mountain ridges at heights between 1000–4000 m (3,300–13,200 ft) altitude, where it nests in colonies beneath overhangs on vertical cliffs, laying three or four white eggs in an enclosed mud nest.
