Rare
Under 5% of wildlife watchers report a Grey-bellied Tesia sighting in Royal Manas National Park on a given day, based on 45 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 245th most-seen of the 388 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.
January and November
In those months about 10% of wildlife watchers report a Grey-bellied Tesia in Royal Manas National Park on a given day, against under 5% in February–July, October and December, the lowest months. Those are among Royal Manas National Park's driest months, with about 20 mm of rain a month against 930 mm in July. August and September have too few records to rate.
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.
6th of 6
Of the 6 parks where we can rate Grey-bellied Tesia sightings, Royal Manas National Park ranks 6th 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 Royal Manas National Park (45 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.
