This is a greater roadrunner (not really sure what the Looney Tunes guys were looking at when they created the cartoon). Roadrunners can fly, but usually don’t, preferring to run across the ground at speeds of up to 15 miles per hour. They got there name due to their habit of emerging from the underbrush along roadsides and running parallel to cars before darting back to safety. I ended up with a chest full of cactus spines after chasing this guy around for about 20 minutes, continually dropping to the ground for eye level shots.
