The lion-tailed macaque (Macaca silenus), locally called wanderoo, is an Old World monkey endemic to the Western Ghats of South India. Lion-tailed macaques are covered in black fur, and have a striking gray or silver mane that surrounds the face in both sexes. The face itself is hairless and black in adults, but pinkish in infants less than a year old. Infants are born with no mane, which begins to growth about two months after birth. They are named not for their mane, but for their tail, which is long, thin, and naked, with a lion-like, black tail tuft at the tip. The size of their tail is about 25 cm (9.8 in) in length. Their eyes are a shade of hazelnut with highlighting black eyelids.
Lion-tailed macaques, like other macaques, have deep cheek pouches used for storing food, and are quadrupedal with opposable digits. The mane that surrounds its face gives this monkey its German name Bartaffe – "beard ape". With a head-body length of 42–61 cm (17–24 in) and a weight of 2–10 kg (4.4–22.0 lb), it ranks among the smaller macaques species.

Possible
About 20% of wildlife watchers report a Lion-tailed Macaque sighting in Periyar National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 14 mammals we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
January
In that month about 50% of wildlife watchers report a Lion-tailed Macaque in Periyar National Park on a given day, against under 5% in February–March and May–September, the lowest months. That is one of Periyar National Park's driest months, with about 25 mm of rain against 410 mm in August.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Lion-tailed Macaque sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Periyar National Park, in our data
Periyar National Park is the only park on Wallace's Line with enough records to rate Lion-tailed Macaque sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Lion-tailed Macaque is recorded against all the mammals logged in Periyar National Park (11 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.
