Two animals, two relatives
Mongolia’s rocky highlands are home to two main wild hoofed animals that travelers tend to group together: the argali, a wild sheep, and the Siberian ibex, a wild goat. They share terrain, look superficially alike from a distance, and are often seen on the same slopes. They are different animals, though, and learning a few differences makes a scan of a ridge far more rewarding.
Argali: the largest wild sheep
The argali is generally regarded as the largest wild sheep in the world. Males carry thick, heavily curled horns that spiral outward, and they are noticeably bulkier than females. The horns grow throughout life and are the reason argali have long been prized by trophy hunters, which has affected populations in many countries. Females also have horns, but they are shorter and more slender.
In Mongolia, argali live in several mountain regions, including the Altai and the Gobi Altai, and in isolated hills in the Gobi and on the edge of the steppe. Different populations are sometimes described as separate forms, and local names vary. Specialists continue to debate how many types exist, so it is best to say simply that argali occur in a number of ranges rather than quoting a precise count.
Argali prefer open, rolling mountain terrain more than sheer cliffs. They eat grasses and other low plants, and they need open views so they can spot predators early. Groups often separate by sex for much of the year, with males forming bachelor groups and females staying with young animals.
Siberian ibex: the cliff specialist
The ibex is a wild goat. Males have long, backward-sweeping horns with ridges across the front, and they often wear a beard and a shaggy coat in winter. Females have much shorter horns. Ibex are more at home on steep, broken cliffs than argali, and they climb with remarkable confidence on slopes that look impossible from below.
Ibex are widespread across Mongolia’s mountain ranges, from the Altai to the Khangai and smaller massifs in the Gobi. They are often seen in small groups, and on a good day a spotter with binoculars can find a dozen on a single cliff face. Their coloring blends into rock, so the best technique is to scan slowly and look for movement rather than shape.
How they live on rocky ground
Both animals share features suited to harsh highlands:
- Hooves with a hard rim and a softer center that grip rock.
- Thick coats that help them tolerate cold winters and wind.
- Social habits that provide extra eyes against danger.
- Seasonal movement between higher summer ranges and lower winter areas, though routes and timing vary by region and year.
Their main natural predators are wolves and snow leopards. Young animals are the most vulnerable, and golden eagles may take lambs and kids. Predators are one reason these animals favor terrain where they can see and run, and the snow leopard article explains how closely the big cat is tied to wild sheep and ibex.
Competition with livestock
In some areas, domestic sheep, goats and other animals graze the same hillsides. Wildlife biologists often point to competition for forage, along with disease risk and disturbance, as concerns where herding and wild populations overlap. This does not mean herders are the problem; pasture is limited, and pasture rights and seasonal moves are part of how herding families manage it. What it does mean is that conservation in Mongolia is almost always a shared-land question. The article on community conservation looks at how local people and rangers work together on this.
Hunting pressure has also affected populations at times, and regulations on hunting and trade are set by authorities and can change. A visitor should never buy horns or other wildlife products, and should check official guidance on what may be taken out of the country.
Where visitors may see them
Sightings are never guaranteed, but the following situations make them more likely:
- Trekking or driving through the Altai and Gobi Altai ranges, including the area around the national park known as Altai Tavan Bogd.
- Walking up side valleys in Gobi mountains, such as those within Gurvansaikhan park.
- Early morning and late afternoon, when animals tend to feed in the open.
- Winter and early spring, when animals can move lower and are sometimes easier to see, although conditions are demanding and travel needs careful planning.
Argali are wary and may flee at long distance. A spotting scope or good binoculars is usually more useful than a camera lens. Stay quiet, keep low, and do not chase animals; stress in winter can cost them scarce energy.
Seeing signs instead of animals
Even when animals are not visible, you may find clues: shed hair on rocks, trails running along a slope, droppings in pellet-like clusters, or old horns. Horns found on the ground in Mongolia are sometimes stacked on cairns or sacred places, and local rules about removing them differ, so leave them where they are and ask your guide.
A note on caution
These mountains are remote and weather turns fast. Anyone walking to look for wildlife should take advice on routes, carry enough supplies and check current conditions with local sources. The wildlife is a reason to go, but safety comes first. For more on how the highland ranges are laid out, a basic grasp of Mongolian geography, with its separate mountain systems and basins, is a useful companion.
