The grizzly bear, also known as the North American brown bear, is a large subspecies of the brown bear found in North America. They are typically found in the continental United States and Canada, primarily in Alaska and western Canada. Grizzly bears can reach weights of 600-800 pounds and are known for their shaggy fur, which can range in color from blonde to black. They are omnivores and their diet consists of both plants and animals, such as berries, roots, fish, and small mammals. They are also known to opportunistically feed on larger mammals such as elk and bison. Grizzly bears are known for their strength and aggression, and are considered dangerous to humans. They are also known for their intelligence and problem-solving abilities. Due to hunting and habitat loss, the grizzly bear population has decreased significantly, and it is now listed as a threatened species under the Endangered Species Act.
