A video shows a herd of approximately 15-20 antelopes, likely Tibetan antelopes (chiru), walking in a single file line across a barren, rocky hillside. The antelopes are light brown with white undersides. One antelope near the middle of the line is clearly visible with long, slender, dark horns, indicative of a male. The ground is rugged, covered with small, loose rocks and sparse, dry vegetation. In the background, rolling hills or mountains are visible under a heavily overcast sky with dark grey clouds. The antelopes move steadily from the left side of the frame towards the right. The scene depicts a high-altitude, arid landscape, characteristic of regions like Hor town, China.
