Grizzly Bears - Surviving Winter

Grizzly bears in North America focus on building fat reserves post-hibernation to survive winter. They consume a wide range of foods, including roots, grass, insects, and clams, but rely heavily on salmon during the midsummer salmon run for protein and fat. In early autumn, berries provide another significant calorie boost. This diverse diet is essential for bears to gain enough weight to endure the five to six months of winter hibernation.
