Chinese researchers filmed a grand "group wedding" of Tibetan antelopes in Tibet. The Northern Tibet Grassland, at an altitude of 5,000 meters, attracts a large number of Tibetan antelopes to mate every winter. Tibetan antelopes only gather at the end of November every year and, one month later, they will return to their respective lives. Polygamy is typical for Tibetan antelopes. Male Tibetan antelopes have to rack their brains to attract females and to prevent mates from running away.
