Likely
About 50% of wildlife watchers report a Capped Langur sighting in Kaziranga National Park on a given day, based on 31 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 16 mammals we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
February and September
In those months about 70% of wildlife watchers report a Capped Langur in Kaziranga National Park on a given day, against about 10% in June and October, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Capped Langur 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.
Among the best
Of the 3 parks where we can rate Capped Langur sightings, Kaziranga National Park ranks 3rd at about 50%, level with the leaders once rounded. The best odds are in Manas National Park (India, about 50%) and Royal Manas National Park (Bhutan, about 50%).
GBIF citizen-science records
It is estimated from how often the Capped Langur is recorded against all the mammals logged in Kaziranga National Park (31 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.
