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.

Likely
About 40% of wildlife watchers report a Gray-throated Martin sighting in Royal Bardia National Park on a given day, based on 123 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 32nd most-seen of the 233 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
May–June and December
In those months about 50% of wildlife watchers report a Gray-throated Martin in Royal Bardia National Park on a given day, against about 30% in February–March, July, September and November, the lowest months. August has 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.
2nd of 12
Of the 12 parks where we can rate Gray-throated Martin sightings, Royal Bardia National Park ranks 2nd at about 40%. The best odds are in Chitwan National Park (Nepal, about 50%). 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 Royal Bardia National Park (123 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.
