The video shows a herd of bison running through a grassy field. The bison are large, brown animals with furry coats and horns on their heads. They are running in a line, with some bison leading and others following behind. The field is vast and open, with no visible trees or other animals. The sky is overcast, and the grass is a mix of green and yellow. The bison appear to be in motion, with their legs and tails visible as they move.
