A Gila Woodpecker works on the side of a saguaro cactus in Tucson, Ariz. The birds peck at the saguaros to create cavities, which they use to raise their young. When the woodpeckers abandon the cavities, other animals move in, including bats, owls and other species of birds.

Sun beginning to set, casting a pale reddish glow on the mountains.
Sunsets in Arizona can be spectacular … unfortunately, there weren’t many clouds in the sky during our entire trip, so the sunsets weren’t as stunning as I had hoped. Still nice, though.
The moon is sometimes visible as early as 1 or 2 p.m. in the desert … however, this shot was taken just before sunset.
