Aldo Starker Leopold (1913–1983) was an author, forester, zoologist and conservationist. He also served as professor at the University of California, Berkeley for thirty years. Throughout his life, Leopold was active in numerous wildlife and conservation groups throughout the United States.

"The avowed objective of the author of this book was "to assemble in one set of covers all that is known to date about the ecology, natural history, and management of the species." To the best of my knowledge, he has succeeded. . . . The book is highly readable, well organized, and will be of interest and value to laymen and professional wildlife managers alike."
