The southern pig-tailed macaque (Macaca nemestrina), also known as the Sundaland pig-tailed macaque and the Sunda pig-tailed macaque, is a medium-sized macaque that lives in Sundaland, southern Thailand, Malaysia, and Indonesia. It is known locally as beruk.
The species epithet, nemestrina, is an adjective (derived from Latin Nemestrinus, meaning "the god of groves") modified to agree in gender with the feminine generic name. M. nemestrina formerly included the northern pig-tailed, Pagai Island, and Siberut macaques as subspecies. All four are now considered separate species.
In the 19th century, bruh was the native name used by Malays in Sumatra for the macaque. As with other Macaca species, males are larger than females; while males are measured at 50–58 cm (20–23 in) in length and 5–12 kg (11–26 lb) in weight, females are measured at 38–48 cm (15–19 in) in length and 4.5–6 kg (9.9–13.2 lb) in weight. This macaque has buff-brown fur, with a darker dorsal area and lighter ventral area. Its common name refers to the short tail held semi-erect, resembling the tail of a pig.

Likely
About 40% of wildlife watchers report a Southern Pig-tailed Macaque sighting in Kerinci Seblat National Park on a given day, based on 24 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 11 mammals we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
January
In that month about 60% of wildlife watchers report a Southern Pig-tailed Macaque in Kerinci Seblat National Park on a given day, against under 5% in March–April and October, the lowest months.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Southern Pig-tailed Macaque sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
4th of 6
Of the 6 parks where we can rate Southern Pig-tailed Macaque sightings, Kerinci Seblat National Park ranks 4th at about 40%. The best odds are in Gunung Leuser National Park (Indonesia, about 60%), Kinabatangan Wildlife Sanctuary (Malaysia, about 50%) and Sepilok (Malaysia, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Southern Pig-tailed Macaque is recorded against all the mammals logged in Kerinci Seblat National Park (24 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.
