The stump-tailed macaque (Macaca arctoides), also called the bear macaque, is a species of macaque native to South Asia and Southeast Asia. In India, they can be found south of the Brahmaputra River, in the northeastern part of the country. The range in India extends from Assam and Meghalaya to eastern Arunachal Pradesh, Nagaland, Manipur, Mizoram and Tripura.
These monkeys are primarily frugivorous but eat many types of vegetation, including seeds, leaves, and roots. They also hunt freshwater crabs, frogs, bird eggs and insects. Stump-tailed macaques have long, thick, fur, and vary widely in their appearance, relative to other primates. Their fur can be gray, brown, reddish, or black, and their faces maybe have freckles or irregular patches. Their short tail ranges between 32 and 69 mm (1.3 and 2.7 in). Like other macaques, they have cheek pouches to store food for short periods of time. Infants are born white and darken as they mature. As they age, their bright pink or red faces darken to brown or nearly black and lose most of the hair. Males are larger than females, measuring 51.7–65 cm (20.4–25.6 in) long and weighing 9.7–10.2 kg (21–22 lb), while females... Wikipedia →

Likely
About 40% of wildlife watchers report a Stump-tailed Macaque sighting in Kaeng Krachan National Park on a given day, based on 165 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 32 mammals we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
November to August
In those months about 40% of wildlife watchers report a Stump-tailed Macaque in Kaeng Krachan National Park on a given day, against under 5% in September, the lowest month.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Stump-tailed Macaque 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.
Only Kaeng Krachan National Park, in our data
Kaeng Krachan National Park is the only park on Wallace's Line with enough records to rate Stump-tailed Macaque sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Stump-tailed Macaque is recorded against all the mammals logged in Kaeng Krachan National Park (165 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.
