This is due South of Tucson, Arizona... and just North of Organ Pipe, National Park... on the Mexican border. Organ Pipe cactus are like the Saguaro, but without any horizontal growths from the trunk.

I agree with the comments above, Doug, except that I've never been to this park. It looks to me like there's a bird on the top of the middle cactus. Perhaps you could consider climbing the cactus next time for a close up of the bird.
