Grizzly bear cubs are born in the den in January or February. Cubs weigh 500 grams (1 lb.) which is less one-tenth as much as human babies and are born blind. Once they have left the womb, the find their way to their mother’s teats where they feed on milk (and grow) until the spring. This photo from early June means the cub is likely less than five months old. The male Grizzly bear’s hibernation ends in early to mid March, while females emerge in April or early May. Although this cub may have been out of the den for little more than one month and is still nursing we observed it eating solid foods.
