Clayton M. White received a B.A. and a Ph.D. in zoology from the University of Utah and did graduate work at University of Alaska. He is Professor of Zoology at Brigham Young University. He worked as a vertebrate ecologist for the U.S. Energy Research and Development Administration on issues dealing largely with arctic oil development. Research includes ecophysiology of finches and ecology and natural history of raptors, primarily falcons. He has served on 2 U.S. Fish and Wildlife Service recovery teams for the Peregrine Falcon. Current address: Department of Zoology, Brigham Young University, Provo, UT 84602. E-mail:

Nancy J. Clum graduated from St. Lawrence University and received M.S. and Ph.D. degrees from Cornell University. Currently she is Assistant Professor of Environmental Science and Biology at DePaul University in Chicago. Her general research interests are in conservation biology and physiological ecology. Her current research concentrates on physiology and population biology of migrating Peregrine Falcons, patterns of growth and development in birds, and habitat structure and use in restored environments. Current address: Environmental Science, DePaul University, 2325 N. Clifton Ave., Chicago, IL 60614. E-mail:

Tom J. Cade received a B.S. from the University of Alaska and M.S. and Ph.D. from the University of California, Los Angeles. He is currently Professor Emeritus of Cornell University and Founding Chairman of The Peregrine Fund, Inc. His studies have ranged from natural history and conservation to physiology in a variety of vertebrates, although his lifelong interest has been birds of prey. He is widely published on those disciplines and is author of The Falcons of the World . In addition to field studies in Africa, Arabia, Central America, Mauritius, Alaska, and the contiguous United States, he is involved in breeding falcons in captivity for release to the wild as a means of preserving rare or endangered species. This work has resulted in successful reintroductions of Peregrine Falcons in the United States and Mauritius Kestrels in Mauritius. Current address: The Peregrine Fund, 566 West Flying Hawk Lane, Boise, ID 83709. E-mail:

W. Grainger Hunt studied Peregrine Falcon migration in coastal Texas for his 1966 master's thesis and received a Ph.D. in zoology from the University of Texas at Austin in 1970, with a specialty in evolutionary genetics. He has studied the ecology of nesting Peregrines in Texas, Mexico, and the California Channel Islands. A commercial pilot, he has tracked Peregrines and Bald Eagles on long-distance migrations and has focused on aerial surveys of habitat selection and survival. He recently completed a 7-year investigation of Golden Eagle ecology, with emphasis on population dynamics modeling. Current address: The Peregrine Fund, 552-205 James Dr., McArthur, CA 96056.
