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.

Possible
About 20% of wildlife watchers report a Gray-throated Martin sighting in Ranthambore National Park on a given day, based on 296 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 75th most-seen of the 251 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February and October
In those months about 30% of wildlife watchers report a Gray-throated Martin in Ranthambore National Park on a given day, against about 10% in April, June–September and November, the lowest months. Those are among Ranthambore National Park's driest months, with about 10 mm of rain a month against 270 mm in August.
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.
3rd of 12
Of the 12 parks where we can rate Gray-throated Martin sightings, Ranthambore National Park ranks 3rd at about 20%. The best odds are in Chitwan National Park (Nepal, about 50%) and Royal Bardia National Park (Nepal, about 40%). All parks ranked.
Same family: Hirundinidae
The closest relatives of the Gray-throated Martin that you can see in Ranthambore National Park (family Hirundinidae, Swallows and Martins) are Dusky Crag Martin (about 20%), Wire-tailed Swallow (about 20%) and Eastern Red-rumped Swallow (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gray-throated Martin is recorded against all the birds logged in Ranthambore National Park (296 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.
