Editor's note: James Horsley, author of "The Buffalo People", adds his voice to the travesty of confining Yellowstone bison to the park.

It is summer in Yellowstone National Park. Some visitors are busy photographing bison and elk grazing together near a multi-colored thermal pool. But their cameras do not record these two ungulates’ radically divergent lives.

Many of the bison have gone through a hazing operation this spring. In the middle of calving season they have been forced back into the park, driven from their historic birthing grounds just outside the park by a coalition of government agents. Every year they converge on horseback and in pick-ups, squad cars and helicopters. Calves are often injured. Uncooperative bison are shot.

Elk on the other hand are left alone to calve and migrate where they please.
