The mainland serow (Capricornis sumatraensis) is a species of serow native to the Himalayas, Southeast Asia and China. The mainland serow is related closely to the red serow. In 1831, Brian Houghton Hodgson first described a goat-like animal with short annulated horns occurring in montane regions between the Sutlej and Teesta Rivers under the name "Bubaline Antelope". As "Bubaline" was preoccupied, he gave it the scientific name Antelope thar a few months later.
When William Ogilby described the genus Capricornis in 1838, he determined the Himalayan serow as type species of this genus. Teeth from a mainland serow were found in a dig in Khok Sung district, estimated to originate from the Middle Pleistocene.
The mainland serow possesses guard hairs on its coat that are bristly or coarse and cover the layer of fur closest to its skin to varying degrees. The animal has a mane that runs from the horns to the middle of the dorsal aspect of the animal between the scapulae covering the skin. The horns are only characteristic of the males and are light-colored, approximately 150 mm (6 in) in length, and curve slightly towards its back. Both male and female... Wikipedia →

Possible
About 30% of wildlife watchers report a Southern Serow sighting in Khao Yai National Park on a given day, based on 331 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 24 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.
March and August
In those months about 40% of wildlife watchers report a Southern Serow in Khao Yai National Park on a given day, against under 5% in September and October, the lowest months.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Southern Serow 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 Khao Yai National Park, in our data
Khao Yai National Park is the only park on Wallace's Line with enough records to rate Southern Serow sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Southern Serow is recorded against all the mammals logged in Khao Yai National Park (331 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.
