That sounds intense! Bison are massive, and they don’t hesitate to assert their presence when they feel threatened or annoyed. In Yellowstone, encounters between bison and cars do happen, and sometimes the bison don’t mind giving a car a little nudge—especially if they’re feeling territorial or just irritated by the presence of vehicles.
These headbutts are often surprising, but it’s a reminder that wild animals are unpredictable and should be respected. Always keep a safe distance when observing wildlife in places like Yellowstone! Was the video you saw part of a more dramatic moment, like the bison getting upset at a slow-moving car, or was it just a random interaction?
