Number 1. We are aware these are bison in the video. Number 2. We are aware the video was edited. Number 3. It’s still a good PSA for those who want to ride the bison at Yellowstone National Park or the Bison Range.
In case you were wondering, here is some information from nationalzoo.si.edu:
Though the terms are often used interchangeably, buffalo and bison are distinct animals. Old World “true” buffalo (Cape buffalo and water buffalo) are native to Africa and Asia. Bison are found in North America and Europe. Both bison and buffalo are in the bovidae family, but the two are not closely related.
