Who is a fan of birds? Whether you are a beginner or a veteran birder, you can find a wondrous variety of birds in Saguaro National Park in Arizona. From birds that are adapted to the extremes of the desert, to birds that prefer the tall pines of the mountains, over 200 species of birds live in or migrate through the park. This owl family looks quite at home in the crook of a large saguaro. Photo courtesy of Jeremy Johnson.
