A few days ago I was cruising around San Angelo State Park when I saw this bird way up, about 45 feet, in the top of a dead tree. When putting my binoculars on it I realized that it was a Greater Roadrunner,Geococcyx californianus). I also noticed that it had a lizard in it’s beak. Perhaps a Racerunner, (Cnemidophorus sexlineatus).
It was too far for my Canon EOS 7D and 100-400mm lens to get a decent shot, so I maneuvered the car in such a way that I could deploy my big Canon 500mm lens with a 1.4 tele-converter attached.
Exposure was 1/2500 sec. @ f6.3, ISO 200. Distance to subject according to my camera data was about 80 feet. Photographed in RAW and processed in Photoshop CS5. Enjoy the photo and if you click on the image you will see an enlargement.
