Evey wonder why desert birds are so angry? Here is your answer. Its hot out here, there is a limited supply of water and every other animal wants to eat you. Look around and maybe you will see a Gila Woodpecker, a Roadrunner, or a Costa's Hummingbird may zoom by. Did you know the Hummingbirds body temperature can be as high as 105 - 109 degrees? This helps them conduct heat in environments like this.
Go get a geocache and start birdwatching.
