The Antilocapra americana, pronghorn, is the fastest animal in the Western Hemisphere and second fastest in the world to the cheetah. Pronghorn is the last member of its biological family, but its population is growing. Wyoming and Yellowstone National Park is place that you can see these animals in their natural habitat.
There are no native buffaloes in America. The animal that use to roam the plains of America is actually a bison bison. Bison bison is the animal's scientific name. The bison was misidentified by our forefathers as buffalo and the name has stuck. One place to see bison roam wild as they did in the 1800s is in Yellowstone National Park. People do call the the bison the American Buffalo. Those into accuracy call the animal displayed in these two pictures bison. Below is a picture of a cow and calf bison herd causing a bison jam in Yellowstone. Bison jams are frequent in Yellowstone as the herds move to different parts of the park or move back and forth to water.
