Siberian brown bears (Ursus arctos collaris) also known as the East Siberian brown bear is a subspecies of brown bear that lives in Eurasia.

These brown bears live in the Altai Mountains (Mongolia), Nothern China, and Eastern Kazakhstan. They can also be found in the Siberian Taiga.


The Siberian brown bear is not as big as the neighboring Kamchatka brown bears however they are larger than brown bears found in Europe. These types of bears have long thick and soft fur which is typically a dark brown color. However, some bears have pale brown, black, or even a cinnamon-like color. A few of Siberian brown bears in the north have white collars.


Siberian brown bears eat both plants and animals. Their diet is made up of seeds, nuts, fruit, roots, tubers, small mammals, carrion, and fish. They are also known to ambush a caribou or elk if needed. These bears are more carnivorous than neighboring brown bears.


Siberian brown bears give birth to 2 or 3 cubs while hibernating. The cubs are born practically hairless and depend on the mother’s thick fur for warmth. They will stay with the mother for about 2 years before going off on their own.


There are roughly 5000 Siberian brown bears living in the Altai mountains and approximately 16,000 in Eastern Siberia. The average life span of the Siberian brown bear is 20 to 30 years in the wild. They are considered to be endangered as they are still largely treated as a game animal.
