Siberian bighorn sheep

It was first described by Russian naturalist Johann Friedrich von Eschscholtz (1793-1831), who explored the Bering Strait region, Kamchatka, Aleutians, Chile and California. They are closely related to North America species such as bighorn sheep.

Siberian bighorn sheep also known as snow sheep or Northeast Asiatic Thinhorned Sheep, a well-adapted mountain dweller, extremely agile and nimble, able to move quickly over steep, uneven terrain.

As in all will sheep, sexual dimorphisms privileges males, which are about 25 percent bigger than females. The males’ horns are much larger and similar to those of the bighorn.

The body weight of rams approaches 150 kg and its height at the withers is about 1 meter in the largest subspecies.

Within bachelor hers, a prominence hierarchy is formed based primarily on horn size. These hierarchies remain relatively stable, even in the bring season, with larger getting the majority of the mating rights.

Siberian bighorn sheep occurs in mountain forest, rocky meadows and bare slopes to 6500 ft in Siberia and northeast Asia, where open meadows for feeding lie adjacent to steep cliffs for resting.
