视频展示了一只麝牛正在吃草的场景。这只麝牛有着浓密的黑色毛发和一对弯曲的角，角的颜色为棕色。它的嘴巴周围有一些白色的毛发，显得非常有特色。麝牛正低头咀嚼着干草，干草的颜色为黄色，看起来非常干燥。在麝牛的左侧有一条银色的铁链，背景是白色的，可能是雪地。
The video shows a close-up of a musk ox eating hay. The musk ox has a thick, dark brown coat and prominent curved horns. It is standing near a chain, likely part of a fence or enclosure. The background appears to be snowy, suggesting a cold environment. The musk ox is calmly chewing on the hay, with its mouth moving rhythmically as it eats.
In a snowy background, a bison with large, curved horns and a thick, dark coat is seen chewing on hay. The bison's head is close to a chain, and it is steadily consuming the hay, moving its mouth and jaw as it eats.
