This Month in Yellowstone
Bob Landis - Bison

It was about 20 degrees F. out as the sun rose on the morning of January 16, 2005. Bob Landis describes bison as his favorite ungulate due to their habit of occasionally kicking up their heals and running around for no good reason. He explained that the bison you see bouncing around in the video were not spooked by a predator or a human but rather just decided it was time to run around a little bit.
