The video shows a close-up of a yak grazing in a grassy field. The yak has a thick, dark coat and prominent curved horns. It is bending down to eat the grass, with its head lowered into the vegetation. The background is filled with green grass and some blurred elements, suggesting a natural outdoor setting. The focus is on the yak's head and upper body as it feeds.
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, moving its mouth to eat the grass. The background is a lush, green field with tall grass and some wildflowers. The bison continues to graze, occasionally lifting its head slightly before resuming eating.
