This is the Grizzly bear, one of the most aggressive of all bears. In fact, the Grizzly is so powerful that it has no natural enemies or predators. This means that the Grizzly doesn't have to worry about being attacked by other animals that may want to eat them.
Grizzly bears spend the spring and summer months looking for food.
They are omnivores, which means that they like to eat both meat and plants. People are omnivores too. When fall comes, Grizzly bears begin to dig out a den that they will hide in during the coldest parts of winter. When winter comes, the Grizzly bear goes inside his den and falls into a deep sleep. But, if the weather isn't too cold, the Grizzly will leave his den in search of food.
