The onager () (Equus hemionus), also known as hemione or Asiatic wild ass, is a species of the family Equidae native to Asia. A member of the subgenus Asinus, the onager was described and given its binomial name by German zoologist Peter Simon Pallas in 1775. Six subspecies are accepted.
The onager is reddish-brown or yellowish-brown and has a broad dorsal stripe on the middle of the back. It weighs about 200–260 kg (440–570 lb) and reaches about 2.1 m (6 ft 11 in) head-body length. It is among the fastest mammals, capable of running 64–70 km/h (40–43 mph).
The onager had a wider range from southwest and central to northern Asia including the Levant region, Arabian Peninsula, Afghanistan and Siberia; the prehistoric European wild ass subspecies ranged through Europe until the Bronze Age. During the early 20th century, it lost most of its range in the Middle East and Eastern Asia and lives today in Iran, Kazakhstan, Uzbekistan, Turkmenistan, India, Mongolia and China. It inhabits deserts and arid regions, grasslands, plains, steppes, and savannahs. Like many other large grazing animals, its range has contracted greatly under the pressures of poaching and habitat loss. It has been classified as Near Threatened on the IUCN Red List in 2015. Two subspecies are extinct, two are endangered, and two are near threatened; its status in China is not well known. Wikipedia →

Likely
About 40% of wildlife watchers report an Asian Wild Ass sighting in Gobi Gurvansaikhan National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 12 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.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Asian Wild Ass sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Gobi Gurvansaikhan National Park, in our data
Gobi Gurvansaikhan National Park is the only park on Wallace's Line with enough records to rate Asian Wild Ass sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Asian Wild Ass is recorded against all the mammals logged in Gobi Gurvansaikhan National Park (8 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.
