Amphibians & Reptiles of Minnesota, Wisconsin & Michigan: A Field Guide to All 77 Species & Subspecies (Paperback) (ISBN-13: 9781936571147)

Allen Blake Sheldon, called "Blake" by family and friends, lives in Trempealeau, Wisconsin, where he roams the Upper Mississippi River National Wildlife & Fish Refuge, Trempealeau National Wildlife Refuge, and Perrot State Park. His enjoyment of amphibians and reptiles began early, with herpetology becoming a major interest during eighth grade. He received a BA in biology from Winona State University, studied Spotted Turtles in Maryland and taught high school biology.

He has been seriously photographing amphibians, reptiles, and other wildlife for over 40 years, mostly in Minnesota and Wisconsin but also in North Carolina, Florida, the Southwest, and Belize. His photos have appeared in National Wildlife, National Geographic, Natural History, Wildlife Conservation, Sierra, Defenders, Audubon, and many other magazines, books, and calendars. He has promoted interest in and understanding of amphibians and reptiles by writing articles for magazines and by presenting programs for environmental and photography groups.
