Kind of a fun scene to come across at the Rocky Mountain Arsenal National Wildlife Refuge near Denver, Colorado recently. Two American Bison bulls were having a bit of a disagreement and got into a tussle. Given that each of these guys weighs more than 1,000 pounds, it probably would not be wise to get between them and try to break it up. 😉
These massive animals were hunted to the brink of extinction in the 1700s and 1800s with as few as 750 reported by 1890. Their numbers have since rebounded with about 500,000 now living on public and private lands.
