Grizzly Mom and Cubs

Female grizzly bears give birth to cubs during their hibernation. Each brand new cub weighs about 1 pound, usually with the births taking place in January or February. By the time they emerge from their hibernation in April or May, after nursing in their den throughout those months, the cubs weigh in at about 20 pounds, and are rambunctious, adorable, and ready to explore their new world.
