Brown brown bear contemplates life in Alaska. NPS Photo / Mike Fitz. With the average male standing up to 7 feet tall and weighing 400-800lbs, the brown bear is one of the largest mammals that makes its home in Bering Land Bridge National Preserve. As omnivores, they are known to prey on fish, elk, moose, and caribou, but about 85% of their diet consists of vegetation and insects. In preparation for their 5-8 month hibernation period, brown bears can gain up to 400lbs in the fall.
