Rare
Under 5% of wildlife watchers report a Pale Sand Martin sighting in Chitwan National Park on a given day, based on 41 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 215th most-seen of the 367 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Pale Sand Martin in Chitwan National Park on a given day, against under 5% in November to September, the lowest months. That is one of Chitwan National Park's driest months, with about 75 mm of rain against 660 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.
2nd of 3
Of the 3 parks where we can rate Pale Sand Martin sightings, Chitwan National Park ranks 2nd at under 5%. The best odds are in Gobi Gurvansaikhan National Park (Mongolia, about 10%).
GBIF citizen-science records
It is estimated from how often the Pale Sand Martin is recorded against all the birds logged in Chitwan National Park (41 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.
