Bison

It looks like the male bison are already in summer form as two of them just threw down in the middle of a snowy Yellowstone National Park road.

It's hard to impress a bison and not necessarily safe to try. You can ask a group of snowmobilers who just recently traversed Yellowstone National Park in a snowstorm. No, the bison they encountered was not impressed.

It's true that bison can be fierce when humans get too close. But, a new video shows they can also be incredibly playful as one Yellowstone winter tour group learned.

One of the largest bison kill sites is buried beneath a neighborhood in Windsor, Colorado.

I fully realize that the pic you're trying to get of a Yellowstone bison up close might be the highlight of your vacation. But, these geniuses are truly tempting fate.

Ever get the feeling that someone is watching you? That must have been the feeling of a bison herd that was recently caught on video being followed by a large Yellowstone wolf pack.
