Catalina State Park, Oro Valley, Arizona
No matter how hard my wife and I concentrate on wildflowers during our desert nature hikes, the prolific and very active lizards of the area seem to clamor for attention. Not wanting to disappoint them, we always stop and give them their due. I'm not sure this fellow intended to put on the comic show he did for us, but it was certainly more enjoyable than watching a wildflower just sit there.
