Robinson's banded langur (Presbytis robinsoni), also known as Robinson's banded surili, is a species of monkey in the family Cercopithecidae. It was formerly considered a subspecies of the Raffles' banded langur Presbytis femoralis, but genetic analysis revealed that it is no more related to Raffles' banded langur than it is to several other Presbytis species. It lives in the northern Malay Peninsula, including southern Burma and Thailand. It is listed as near threatened by the IUCN. Wikipedia →

Possible
About 30% of wildlife watchers report a Robinson’s Banded Langur sighting in Kaeng Krachan National Park on a given day, based on 96 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 32 mammals we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
February–March and November–December
In those months about 40% of wildlife watchers report a Robinson’s Banded Langur in Kaeng Krachan National Park on a given day, against under 5% in August to October, the lowest months. Those are among Kaeng Krachan National Park's driest months, with about 60 mm of rain a month against 260 mm in September.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Robinson’s Banded Langur sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Yes
Of the 2 parks where we can rate Robinson’s Banded Langur sightings, Kaeng Krachan National Park has the highest daily chance: about 30%. Next come Khao Sok National Park (Thailand, about 10%).

GBIF citizen-science records
It is estimated from how often the Robinson’s Banded Langur is recorded against all the mammals logged in Kaeng Krachan National Park (96 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.
