The Onager: An Overview
Native to Iran, this species was once common throughout Central Asia and the Middle East (The Wilds 2018), but now the population is endangered and only an estimated 600 to 700 individuals are left in the world today (Columbus Zoo and Aquarium 2018).
Currently, the majority of the Onagers in the wild live in two protected areas in Iran (Smithsonian’s National Zoo & Conservation Biology Institute 2018) and less than a hundred live at zoos around the globe (Righthand 2010).
At first glance, one might confuse them with a donkey, but they’re actually a subspecies of the Asiatic wild horse.
Onagers have a distinct appearance with buff color coats and a lighter color on their legs and stomach. They have a brown dorsal stripe along their back and a short, brown mane that stands up straight. Their medium-length tail has a tuft that starts part way down. In warm weather, their coat is short but it becomes thick in the winter for protection from the cold.

Have you ever seen an Onager?
Current Conservation Status
According to the IUCN Red List of Threatened Species (2015), the Onager's conservation status is “Endangered”.
The IUCN Red List of Threatened Species previously categorized them as "Critically Endangered" (2002).
The Future of This Species
The Onager's future depends on protecting those that remain in the wild and the success of breeding programs at zoos and wildlife conservation centers around the world.
In the Wild
Although most of the Onagers in the wild live in two protected areas in Iran, the population continues face numerous threats to their survival.
Some of these threats include:
- Habitat loss due to competition for land with domestic livestock and humans
- Environmental conditions such as drought, causing limited food and water supply
- Health issues due to inbreeding or diseases passed on from farm animals
In June 2018, the General Director for Environmental Protection of the Fars Province in Iran introduced new measures to protect this species in the Bahram-e Gur Protected Area. These measures include providing food and water to Onagers in this drought-stricken region, installing warning panels and distributing materials to drivers in these areas (Rezaian 2018).
Protection efforts in Iran’s Touran Wildlife Refuge have already made a positive difference. In 2017, the director of the refuge in Touran announced that the Onager population has doubled in the last ten years (Financial Times 2017).
The continuation of measures to protect these horses and stopping poaching are vital to preventing them from becoming extinct in the future.
Breeding programs at zoos and wildlife conservation centers are also crucial to sustaining and increasing the population. Onager foals in the wild have a mortality rate of 50%, but those born in captivity have better odds of survival (Smithsonian’s National Zoo & Biology Conservation Institute 2011).
Onagers in zoos serve as an insurance policy against catastrophic loss in the wild...— Dr. Mandi Vick, Cleveland Metroparks Zoo
Interesting Things to Know
- Onagers are sometimes referred to as “Persian Zebras."
- They're also sometimes called “Gur,” which means “swift” in the Persian language (Wikipedia Persian onager 2018).
- The tuft at the end of their tail can be used as a flyswatter (Columbus Zoo and Aquarium 2018).
- They can run up to 70 kilometers per hour (43 miles per hour) (Wikipedia Onager 2018). That's nearly as fast as the Guinness World Records fastest recorded speed of a racehorse, which is 70.76 kilometers per hour (Guinness World Records 2018).
- They're sturdy animals that can handle living in temperature extremes. Built for desert conditions, they can survive in 120-degree heat (Cleveland Metroparks Zoo 2018).
- Foals are able to run shortly after they're born (Smithsonian’s National Zoo & Conservation Biology Institute 2018).
What Zoos Have Onagers?
If you'd like to see these beautiful horses at a zoo or wildlife park, here are a few locations where you can find them:
- Chester Zoo in Upton by Chester in Cheshire, England, U.K.
- Cleveland Metroparks Zoo in Cleveland, Ohio, USA
- Greater Vancouver Zoo in Aldergrove, BC, Canada
- Parc Safari in Hemmingford, Quebec, Canada
- Rostov Zoo in Rostov-on-Don, Russia
- Taroga Western Plains Zoo in Dubbo, NSW, Australia
- Tehran Zoological Garden (Eram Zoo) Near Eram Park in Tehran, Iran
- The Wilds in Cumberland, Ohio, USA
- Zoo Augsburg in Germany
Note: Animal exhibits at these places change from time to time, so you might want to check to see if they currently have Onagers before visiting.
