These photos were shot over a 61-minute period in Wind Cave National Park this Christmas Eve(ning). The elk is a 6×6.

I have heard of wolves doing what I saw this coyote doing. I think he was hunting mice or some other small creature. The nearest prairie dog town was about 400 feet away. He would be very still for a while, then would suddenly leap a foot or two up in the air, and forward, then come down with his nose right at the ground.

The animals are, top to bottom:  elk, coyote, pronghorn antelope, white tail deer, and bison.
