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 Prayagraj on a given day, based on 31 verified sightings from GBIF citizen-science data. It is the 79th most-seen of the 139 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
December
In that month about 30% of wildlife watchers report a Gray-throated Martin in Prayagraj on a given day, against under 5% in February, April–August and October–November, the lowest months. That is one of Prayagraj's driest months, with about 5 mm of rain against 260 mm in July.
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.
6th of 21
Of the 21 cities where we can rate Gray-throated Martin sightings, Prayagraj ranks 6th at about 10%. The best odds are in Hanoi (Vietnam, about 30%), Taichung (Taiwan, about 20%) and Lucknow (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Gray-throated Martin is recorded against all the birds logged in Prayagraj (31 verified sightings), 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.
