The video shows a close-up of a yak grazing in a grassy field. The yak has thick, dark fur and prominent curved horns. It is bending down to eat the grass, with its head lowered into the vegetation. The background features a blurred view of more grass and some rocks, indicating a natural, outdoor setting. The scene captures the peaceful activity of the yak in its natural habitat.
A bison with large, curved horns and a black and white coat is seen grazing in a grassy field. The bison lowers its head to the ground, using its mouth to eat the grass. The bison continues to graze, moving its head slightly as it eats. The bison then begins to slowly move forward while still keeping its head close to the ground. The background consists of green grass and some taller, dry grass, with a blurred, natural landscape.
