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 Myanmar, northern Vietnam, and just into China. It occurs in river valleys and rugged wooded mountain ridges at heights between 1,000–4,000 m (3,300–13,100 ft) altitude, where it nests in colonies beneath overhangs on vertical cliffs, laying three or four white eggs in an enclosed mud nest.
This martin has blue-black upperparts with a contrasting white rump, and white underparts. It resembles its close relatives, the Asian house martin and common house martin, but unlike those species it has a black throat and black undertail. It feeds in flocks with other swallows, catching flies and other insects in flight. It is subject to predation and parasites, but its status within its limited range appears secure.
The Nepal house martin was first described by British entomologist Frederic Moore in 1854, and placed in a new genus Delichon created by Moore and American naturalist Thomas Horsfield. The specimen or its description was attributed by Moore to Brian Houghton Hodgson and early literature... Wikipedia →

With luck
About 10% of wildlife watchers report a Nepal House Martin sighting in Royal Manas National Park on a given day, based on 63 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 194th most-seen of the 388 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
October
In that month about 20% of wildlife watchers report a Nepal House Martin in Royal Manas National Park on a given day, against under 5% in April, June–July and November–January, the lowest months. That is one of Royal Manas National Park's driest months, with about 130 mm of rain against 930 mm in July. August and September have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Nepal House Martin sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 6
Of the 6 parks where we can rate Nepal House Martin sightings, Royal Manas National Park ranks 2nd at about 10%. The best odds are in Langtang National Park (Nepal, about 20%).
GBIF citizen-science records
It is estimated from how often the Nepal House Martin is recorded against all the birds logged in Royal Manas National Park (63 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
