Lizards in the yard

Jacen and I were doing some yard work this morning when I spotted a lizard running across the road. While Jacen kept an eye on him, I ran and got my camera. We actually saw three of these guys, but this one was the most photogenic. He was an adept tree climber and obviously a male, as he kept trying to intimidate Jacen and I by bobbing his head around and inflating the air sac under his throat. If you can identify what type of lizard he is, leave me a comment, please.
