You never know what you'll see when you take a trip to Yellowstone National Park. There are endless opportunities to witness wildlife interact in their natural habitat.

Personally, I've witnessed wolves running after a herd of antelope, and have seen quite a few grizzly bears as well.

Visitors make the trek to Yellowstone from all over the world to catch a glimpse of the abundance of wildlife.

Recently, YouTube user Deby Dixon witnessed a pretty spectacular sight. First, she witnessed a bison give birth. After that, things got a little more interesting. Both a coyote and a grizzly bear were in the area and began to stalk the bison calf.
