Bison are easily aggravated during their mating season, as one family learned the hard way during a visit to Yellowstone National Park. The two adults and two children make the mistake of getting too close to a bull during the rut, and ended up being chased between trees by the agitated animal.
A video of the incident, shared via Instagram account TouronsOfNationalParks this week, shows the animal charging with its rail raised and head bobbing in a characteristic display of aggression, narrowly avoiding trampling a young girl. In the clip, which you can see below, you can see the bison driving the visitors away in clouds of dust before eventually leaving the area.
