Habitat
The wild Przewalski’s wild ass is found in Mongolia, Asia. Most of them are now domesticated, and photos can be seen online. They sometimes appear on the news in Japan.
- Geographic Distribution
Mongolian Plateau: Central Mongolia, northern Gobi Desert
Northern China: Southern Gobi Desert, Inner Mongolia Autonomous Region
Kazakh Grassland (partially)
Once more widespread, their range has shrunk due to human development and hunting.
💡 Key Points: Wild donkeys have adapted to arid zones, grasslands, and deserts.
- Habitat
Arid Grassland: Eats shrubs and dry grasses.
Semi-desert and desert edges: Live mainly in areas with scattered water sources.
Altitude: Generally plateaus between 500 and 1,500 meters.
Travels widely in search of water and food.
- Ecological Relationship
Requires a wide range of movement: Because food and water are scattered in arid areas,
They often live in packs, congregating at water sources and salt pools.
To protect themselves from predators (such as wolves), they remain cautious even in open grasslands.
What are its characteristics? What does it look like?
The Przewalski’s wild ass is a subspecies of the Asian wild ass, which is widely distributed throughout Asia. Its limbs are thin and long, and its coat is pale yellowish brown or pale reddish brown, turning gray in winter. Its mane and tail are black. Its front legs have black calluses on the inside, as seen on horses. The Przewalski’s wild ass mainly lives around the Gobi Desert, in semi-desert areas, wastelands, and river valleys.

💡 Key Points: Their body coloration allows them to blend in well with dry areas and grasslands, making them difficult to spot even from afar
- Physical Adaptations
Tolerant of dry and cold environments
Thick fur allows them to withstand winter cold
Able to survive in environments with little grass or water
Highly capable of long-distance migration
Travels across vast grasslands in search of food and water
- Personality and Behavioral Characteristics
Shy but cautious
Quickly flees when detecting predators or humans
Typically lives in groups
There is a social hierarchy within the group, with a leader leading the group
Predominantly diurnal
Eats and moves during the day, resting at night
- Diet
Herbivore
Eats mainly grasses, shrubs, and leaves in arid regions

Drought-tolerant, can sometimes survive on the moisture in grass alone
What is its personality like?
Przewalski’s wild asses are very social animals, and live in groups of around 10.
- Highly Cautious
As wild animals, they are extremely timid and cautious.
They quickly flee when predators (wolves, leopards, humans, etc.) approach.
They carefully observe their surroundings, ensuring safety even in open grasslands.
💡 Key point: They always act cautiously to protect themselves from predators.
- Sociality in Groups
They often live in groups.
Primary groups are usually matriarchal, consisting of 10-20 individuals.
Each group has a leader (usually a male) who coordinates their activities.
They have a sense of social hierarchy and territoriality, and maintain order within the group.
- Timid but Adaptable
They are well-adapted to life in groups and on vast grasslands, and will quickly flee if they sense danger.
They are sensitive to changes in humans and the environment and can become stressed.
On the other hand, they have a high ability to survive in dry and cold regions.
- Behavioral Characteristics
Primarily diurnal.
They eat and travel in groups, remaining wary of each other.
They are low-aggression and avoid conflict.
What is its ecology like?
Przewalski’s wild asses live on grass and other plants. They breed from April to October and are monogamous. They are 11 to 12 months pregnant, and can give birth to one baby at a time. The babies are weaned at 9 to 12 months. They can live for over 20 years in captivity.
- Behavior
Diurnal, active during the day
Living in groups, eating and traveling as a group
Traveling long distances across vast grasslands and arid lands in search of water and food
- Housing/Hiding Places
Living in grasslands and scrub areas on the edge of deserts
With few hiding places, vigilance and the ability to flee quickly are key to survival
Resting at night to prepare for daytime activity
- Diet
Herbivore: Eating leaves, stems, and branches of dry grasslands and shrubs
Regularly gathering at salt and water sources to obtain salt and moisture
Can survive to some extent on the moisture of grass alone, but are more active when water is available
- Social/School Behavior
Schools are primarily matriarchal, with males protecting the group
There is a social hierarchy within the group, with leaders directing their behavior
Cooperating when guarding against predators or traveling long distances
- Breeding
Mating season is from spring to summer.
Gestation period: Approximately 11 months.
Give birth to one pup at a time.
The young grow up under the protection of their mother and pack, and begin to move independently within a few months.
Do they have any natural enemies?
The natural enemies of the Przewalski’s wild ass are wolves and other animals. They have excellent eyesight and hearing, are quick to sense danger, and can run at speeds of up to 60-70km per hour.

Are Przewalski’s wild asses endangered?
Przewalski’s wild asses are designated as endangered. Poaching for meat is the biggest threat, and conservation efforts are underway.
- International Assessment (IUCN Red List)
Classification: Treated as a subspecies
Conservation Status: Endangered (Critically Endangered)
Explanation:
Populations are declining due to habitat loss and poaching.
Distribution is particularly limited in the Mongolian Plateau and northern China.
- Population Size and Distribution
Wild population estimated at several thousand individuals (exact numbers are difficult to determine).
Locally inhabits the Gobi Desert and the dry grasslands of Central Asia.
Distribution has shrunk since the past, and human activity has had a significant impact.
- Threats
Deforestation and Grassland Development: Habitat destruction due to livestock farming and agricultural land development.
Poaching and Capture: Targeted for meat, skin, and sometimes pets.
Climate Change and Drying: Survival is difficult in areas with limited water and food sources.
Can Przewalski’s wild asses be kept as pets?
Przewalski’s wild asses are designated as endangered, so the general public cannot keep them as pets. They are listed at the top of the homepage of zoos and other places, so take a look at males and females.
- Personality and Behavioral Issues
Highly wary
Sensitive to predators and humans, and easily stressed
Strong wild instincts, timid, and quick to flee
Vulnerable to environmental changes and contact, they cannot adapt to a home environment
According to their behavioral needs, they are designed to live in groups
Understanding significant mental and behavioral stress when kept alone
💡 Key Point: Their personality makes them unsuitable as pets
- Environmental Issues
They need the ability to navigate vast grasslands and arid areas
Crowded enclosures can lead to health problems due to lack of exercise and stress
Water and salt sources are necessary
Because they are adapted to life in arid areas, a specific environment is essential
- Laws and Regulations
They are protected as an endangered species in many countries
In Japan, under the Convention on International Trade in Endangered Species (CITES), special permission is required for import and breeding
Keeping them only in zoos and conservation facilities; private ownership is generally prohibited
