Nature seems to have some of the most powerful motherhood moments. This grizzly was close approaching a cow moose and her calves when the mother turned, charged, and chased the bear away.
If you need any more evidence that moose are not to be trifled with, there it is. Cow moose typically weigh around 836 pounds on average, while male grizzly bears typically weigh around 400-600 pounds, so that moose could easily have the weight advantage. Plus, a kick from one of those animals can cause some serious damage.
