An authority on birds and larger mammals of the world, Alden has authored 15 books on North American and African wildlife, including the National Audubon Society’s Regional Field Guide Series. His creation of the world’s first Biodiversity Day event at Waldon Pond in 1998 has inspired similar events across the nation and in over a dozen other countries.
