Grizzly bear twins explore a meadow near Haines, Alaska. These immature grizzly bear twins were only born six months ago. Despite their young age, the twin bears are already fairly large. They look like adolescents, if not full-grown adults yet.
Grizzly bears weigh around one pound when they are born, and are roughly the size of a chipmunk. Bears are born while their mother hibernates, and the young cubs will nurse for several months while their mother slumbers. Grizzlies can give birth to anywhere between one and four cubs in a litter, but bear twins or triplets are most common.
Many grizzly bear cubs will die before they turn one year old.
