Did you know that the turkey vulture has been seen by pilots soaring as high as 20,000 feet? Or that the Greater Roadrunner scoots along on two spindly legs at speeds of up to 15 miles per hour as it chases down rattlesnakes and hummingbirds for food? These and 143 other species of birds found in the U.S. Southwest are featured in this handy field guide. Arizona birding experts Kurt and Cindy Radamaker have co-authored this easy-to-use guide, which features accurate color illustrations of each species along with range maps and text on characteristics and natural history.
