Bison Fight for Mating Rights | BBC Earth

For most of the year, bison bulls and cows live separate lives... but for a few weeks in late summer... thousands congregate in this Yellowstone Valley. It's the rut, the mating season... and the biggest bulls are busy guarding their harems. A dominant bull might mate with over 50 females. For the calves born this year, now is the time to stretch their young legs. But as the herd grows, so tensions rise. The rut takes a heavy toll on the big bulls. So, arriving now could give this young contender an edge. But there's life in the old bull yet. Head-to-head, the challenger more than holds his own. Then he makes a small mistake. Shunted aside, his challenge is brutally ended. The young bull gambled everything and has paid a heavy price.
