A group of campers have been caught on camera harassing bison at Badlands National Park, on the same day a woman was gored and seriously injured by one of the animals at Yellowstone.
In a photo taken by another park visitor, a large group can be seen crowding around a bison grazing near their tent, surrounding it from all angles. Bison generally prefer to avoid close contact with people, but like all wild animals they can become aggressive if threatened, which might happen if they have no easy route to escape an uncomfortable situation.
