The grey-throated martin or Asian plain martin (Riparia chinensis) is a small passerine bird in the swallow family. The grey-throated martin is found in open habitats such as farmland, grassland and savannah, usually near water. It is found from Tajikistan, Afghanistan and Indian subcontinent to southern China, Taiwan, and the northern Philippines. It was formerly considered a subspecies of the plain martin, since renamed the brown-throated martin.

With luck
About 10% of wildlife watchers report a Gray-throated Martin sighting in Namdapha National Park on a given day, based on 60 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 166th most-seen of the 298 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March–April and November
In those months about 10% of wildlife watchers report a Gray-throated Martin in Namdapha National Park on a given day, against under 5% in May, October and December–February, the lowest months. Those are among Namdapha National Park's driest months, with about 140 mm of rain a month against 660 mm in July. June to September have too few records to rate.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Gray-throated Martin sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
7th of 12
Of the 12 parks where we can rate Gray-throated Martin sightings, Namdapha National Park ranks 7th at about 10%. The best odds are in Chitwan National Park (Nepal, about 50%), Royal Bardia National Park (Nepal, about 40%) and Ranthambore National Park (India, about 20%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Gray-throated Martin is recorded against all the birds logged in Namdapha National Park (60 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.
