The safest way to appreciate wildlife at Yellowstone National Park is from the safety of a car – you never know when a bison might take exception to your presence, as one visitor discovered earlier this year. The incident was captured during the animals' mating season, known as the rut, which lasts from June to September. During this time males are particularly aggressive as they attempt to assert dominance and fight for mating rights.
The vehicular attack (which you can watch below) was shared on Instagram account TouronsOfYellowstone this week. The page usually highlights examples of bad behavior at US National Parks and other sites of natural beauty, but also posts close encounters with wildlife that takes a dislike to humans without provocation.
