A man was seriously injured on Friday evening at Yellowstone National Park after an agitated bull bison chased him through a campground and hurled him several feet into the air. The incident, which was captured on video, stands out because — unlike many viral Yellowstone clips of tourists behaving recklessly near wildlife — the report frames this as an encounter in which the visitor was not obviously provoking the animal.

According to the article, the attack took place at a campground within the park, and footage credited to NewsFlare shows the bison charging and headbutting the man, launching him into the air. Bison are among Yellowstone's most dangerous animals and are responsible for injuring more visitors than any other species in the park. The available text does not provide further details on the man's condition, his identity or any response from park officials.
