This was the only shot that showed the pretty red stripe that goes down the sides of the roadrunners head. More interesting facts from the Cornell site: "The roadrunner’s distinctive X-shaped footprint—with two toes pointing forward and two backward—are used as sacred symbols by Pueblo tribes to ward off evil. The X shape disguises the direction the bird is heading, and is thought to prevent evil spirits from following." You can see the two back pointing toes on the fence in this shot.
