David H. Ellis grew up in eagle country in the Rocky Mountain West and was fascinated by golden eagles from early childhood. His Ph.D. dissertation is a monograph on golden eagle behavior. He has lived in 11 U.S. states and has visited all of them, as well as 50 nations, generally in pursuit of bird (mostly raptor) research. These travels involved work with harpy eagles in Central and South America, bald and golden eagles in Alaska and Canada, and golden eagles in the U.S., Japan, Siberia, and, most of all, Mongolia. His falcon research focused on pallid falcons in Patagonia, saker falcons in Mongolia, and peregrine falcon populations in Arizona. His publications exceed 300 articles, chapters, or books, including three volumes on crane research.
