Rare
Under 5% of wildlife watchers report a Grey-bellied Tesia sighting in Jim Corbett National Park on a given day, based on 110 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 188th most-seen of the 368 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
November to March
In those months about 10% of wildlife watchers report a Grey-bellied Tesia in Jim Corbett National Park on a given day, against under 5% in April to October, the lowest months. Those are among Jim Corbett National Park's driest months, with about 25 mm of rain a month against 360 mm in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Grey-bellied Tesia sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 6
Of the 6 parks where we can rate Grey-bellied Tesia sightings, Jim Corbett National Park ranks 4th at under 5%. The best odds are in Namdapha National Park (India, about 10%), Manas National Park (India, about 10%) and Langtang National Park (Nepal, about 10%).
GBIF citizen-science records
It is estimated from how often the Grey-bellied Tesia is recorded against all the birds logged in Jim Corbett National Park (110 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.
