Was out hunting with my dad tonight and seen a grizzly bear 40 minutes outside of Whitecourt Ab. Got the camera recording and drove up to him only to find him digging the roof off a bear den that had a black bear sow and three cubs cornered inside of it. In the video the sow tried to fight her way out and one of the cubs tried to make his escape. The grizzly got the one cub but the sow and other two cubs made it away. Craziest thing to watch from less the ten yards away sitting in the truck. #nature #grizzly #blackbear #naturalselection #bearkillscub #outdoors #alberta #insanefootage
