Southern Arizona in the winter months is a great place for Birding. On an outing into the desert at Catalina State Park one can find numerous different birds. Some are resident while many are migratory. If you are a birder I recommend this Park for its many different birds. Camera was a Canon 5D Mk III with a Canon 500mm f4 lens on a tripod. Settings as follows. Aperture was 5.6, speed was 1/640 sec and ISO was at 200.
