Young Grizzly Bear cubs play with each other as their mother fishes for salmon on a river in Southeast Alaska. These yearling cubs will soon leave the protection of their mother.
Although they look to be of different seizes, these bears are siblings. The big grizzly bear cub has is larger than his sibling, but in human terms, we would consider these bears twins. A grizzly bear mother will not have new cubs until her old ones have left her behind to lead solitary lives. This behavior prevents the cubs from attacking one another or being too mismatched in terms of life development.
