The Grizzly Bear is a powerful predator, capable of out sprinting a horse, and weighing as much as 350-600 pounds.
Grizzlies are omnivorous, meaning they eat both meat and plants.
In Yellowstone, grizzlies feed on elk, trout, bison carrion, pinenuts, grasses, roots, and berries. Certain characteristics distinguish grizzlies from black bears. The grizzly is larger, both in girth and weight. The grizzly's coat ranges from tawny cinnamon to light brown or even black. A feature also associated with grizzlies is the shoulder hump, and area of well- defined muscle.
