Frank L. Beebe, the falconer, for 40 years has been one of North America's leading falconers. His previous books on the subject are largely responsible for the present status and popularity of this ancient sport. He is not only a leading Peale's and Gyr falcon researcher but has been a pioneer falcon breeder. Probably more falconers and nature lovers have original Beebe paintings than those of any other artist. Few persons have experienced, let alone been able to capture with paint, the intricate working of the predator-prey responses as Frank.
