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 →

Rare
Under 5% of wildlife watchers report a Nepal House Martin sighting in Jim Corbett National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 340th most-seen of the 368 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Nepal House Martin in Jim Corbett National Park on a given day, so our monthly data shows no clear season.
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.
6th of 6
Of the 6 parks where we can rate Nepal House Martin sightings, Jim Corbett National Park ranks 6th at under 5%. The best odds are in Langtang National Park (Nepal, about 20%), Royal Manas National Park (Bhutan, about 10%) and Namdapha National Park (India, under 5%).
Same family: Hirundinidae
The closest relatives of the Nepal House Martin that you can see in Jim Corbett National Park (family Hirundinidae, Swallows and Martins) are Eastern Red-rumped Swallow (about 20%), Gray-throated Martin (about 20%) and Barn Swallow (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Nepal House Martin is recorded against all the birds logged in Jim Corbett National Park (7 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.
