Rare
Under 5% of wildlife watchers report a Pale Sand Martin sighting in Jim Corbett National Park on a given day, based on 39 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 244th most-seen of the 368 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
March
In that month about 10% of wildlife watchers report a Pale Sand Martin in Jim Corbett National Park on a given day, against under 5% in April to February, the lowest months. That is one of Jim Corbett National Park's driest months, with about 35 mm of rain against 360 mm in July.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Pale Sand Martin sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Pale Sand Martin sightings, Jim Corbett National Park ranks 3rd at under 5%. The best odds are in Gobi Gurvansaikhan National Park (Mongolia, about 10%) and Chitwan National Park (Nepal, under 5%).
GBIF citizen-science records
It is estimated from how often the Pale Sand Martin is recorded against all the birds logged in Jim Corbett National Park (39 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.
