I've never seen anything quite like this before. A new video share from Yellowstone National Park seems to show a bison bull chasing off wolves and bears after one of their own is fallen.
It's hard to impress a bison and not necessarily safe to try. You can ask a group of snowmobilers who just recently traversed Yellowstone National Park in a snowstorm. No, the bison they encountered was not impressed.
It's true that bison can be fierce when humans get too close. But, a new video shows they can also be incredibly playful as one Yellowstone winter tour group learned.
