Roadrunner, Anza-Borrego State Park, CaliforniaThere are two species of roadrunner in the world, the greater and the lesser roadrunner. This is the former. I photographed this guy in Anza-Borrego State Park in southern California. True to his name, he was running across the desert floor, presumably looking for something to eat. Nikon D800 with Nikkor 200-400mm lens (at 260mm) ISO 800, f/4 at 1/800th of a second.
