Nora Mays Bowers is a writer and nature photographer. She likes being outdoors-looking at birds, wildlife, and plants.

She is the primary author of Wildflowers of Arizona, Wildflowers of the Carolinas, Wildflowers of Texas, Cactus of Texas, Cactus of the Southwest, and Kaufman Focus Guides: Mammals of North America.

After college, Rick led bird-watching tours for Victor Emanuel Nature Tours for 16 years. Now, when not working on books or photography, Rick leads photography and birding tours around the world through his company, Bowers Birding & Photo Safaris.
