Grizzly bears are a kind of brown bear that live in North America, mostly in Alaska and western Canada. Grizzly bears live alone, except for mothers and their cubs. Cubs live with their mother until they are 2 or 3 years old. Grizzly bears are omnivores. They eat both meat and plants. They like nuts, berries, and salmon. They will also hunt deer, moose and elk. They eat a lot of food in summer and fall to prepare for hibernation. They can eat for up to 20 hours a day! Grizzly bears have a lump of muscle on their backs that they get from digging. In winter, grizzlies use their claws to dig a den to hibernate in. Grizzlies can hibernate for up to six months. They do not eat or even go to the bathroom during this time! When spring rolls around the male grizzles leave their dens in March while the females and their cubs leave theirs in April or May. Now it's time to look for food. After that long rest they are hungry!
