Southeast Arizona experiences unique changes throughout the seasons.  What are your favorite seasonal hallmarks; hummingbirds at your backyard feeder in winter, Mexican free-tailed bats emerging from bridges on summer evenings, Monsoon wildflowers?  Have you noticed how these events change with local weather and annual climate?  Join us for a conversation about observing birds, insects, plants, and other animals in the Sonoran Desert and Sky Islands throughout our changing seasons.  Learn how to keep track of your observations in the ecosystem to better understand how a changing climate may be affecting some of your favorite species. 

This talk was delivered at the 2013 Tucson Audubon's Bird and Wildlife Festival.
