About the Author(s)

Tom J. Cade is Professor Emeritus of Cornell University and Founding Chairman of The Peregrine Fund, Inc. A graduate of the University of Alaska, he received his M.A. and Ph.D. degrees from the University of California, Los Angeles. Although he has studied topics ranging from natural history to physiology in a variety of vertebrates, his lifelong interest has been in birds of prey. In addition to field studies carried out in Alaska, Africa, Arabia, Central America, Mauritius and the southwestern United States, he has addressed problems involved with breeding large falcons in captivity with the aim of preserving rare or endangered species by means of domestic propagation and release of progeny to the wild. This work has resulted in the successful reintroduction of endangered species such as the Peregrine Falcon in the United States, and the Mauritius Kestrel in Mauritius. He continues to supervise work designed to further the study and preservation of birds of prey. Current address: The Peregrine Fund, 5668 West Flying Hawk Lane, Boise, ID 83709.

A graduate of St. Lawrence University, she received her M.S. and Ph.D. degrees from Cornell University. Her general research interests are in conservation biology and physiological ecology. Her current research concentrates on the nutritional physiology and ecology of birds, and analysis of long-term trends in reproduction, with emphasis on threatened and endangered species. She anticipates eventually having an author’s note as long as that of her co-author and mentor.
