Three separate clips of bears using a tree for a scratching post at Heil Valley Ranch in Boulder County, Colorado. Bears rub trees to mark them, that advertises their presence to other bears. Video was captured using a motion-activated camera by Jesse Lewis, a graduate student at Colorado State University, conducting research.
Note: There is no audio.
