The Grizzly Bear (Usus Arctos horribilis), also known as the North American Brown Bear, is a large population of brown bear inhabiting North America. They are a very large bear with the male weighing from 400 - 790 pounds and the females from 290 - 400 pounds. The Lewis and Clark expedition named the bear "grisley" but probably meant grisly which means fear-inspiring or gruesome. Although grizzly bears are classified as and have the digestive system of carnivores they eat both plants and animals. They will even eat carrion left behind by other animals. They are very opportunistic feeders eating whatever they can find. Grizzly bears normally hibernate for 5-7 months each year, especially in a colder climate. This grizzly bear was photographed while foraging in Glacier National Park, Montana, USA.
