Yellowstone's grizzly bear population got a boost this year when one sow birthed a litter of five cubs – and one lucky guide recently got a perfect shot of the family while out with guests.
In an Instagram video which you can watch below, wildlife naturalist guide Bo Welden captures the moment the so-called grizzly bear "supermom" crosses a felled tree in the woods. Moments later, her first cub follows her, then each adorable sibling crosses the log in turn, much to the delight of the spectators who you can hear squealing with delight behind the camera.
