Brown bears live throughout Gates of the Arctic. However, there are higher populations along most of the Park's major streams and rivers. Because their food is so spread out, there is an average of one brown bear for each 100 square miles. Brown bears spend much of the summer adding layers of fat to their body by eating anything they can find, including roots, berries, fish, small mammals, and if they are lucky, the calves of moose and caribou. The winter is spent sleeping in their dens while their body burns the fat they stored in the summer. This is not considered true hibernation because they occasionally wake up and move around in the den. During this time, the bear's heart rate slows, they don't eat or use the bathroom, and female bears give birth without fully waking up.
