In the video, two large bison are seen fighting each other in a grassy field. They are pushing against each other with their heads and horns, causing a cloud of dust to rise around them. The bison are dark brown in color and appear to be quite powerful as they continue to push and shove each other. The grassy field is green and appears to be quite vast, with no other animals or objects in sight. The bison are the main focus of the video, and their actions are the main event.
