The video shows a group of bison walking across a grassy field. The bison are large and brown, with thick fur and large horns. They are walking slowly and calmly, grazing on the grass as they go. The field is vast and open, with no other animals or people in sight. The sky is overcast, and the lighting is soft and natural. The bison are the main focus of the video, and their movements are the only action taking place.
