1979 edition. Donald S. Heintzelman describes and depicts the species of hawks, owls, vultures, kites, eagles, ospreys, and caracaras that are native to the United States and Canada, as well as those species that are rarely seen in North America.  In addition, he examines their ecology and migrations more generally and discusses fossil hawks and owls, endangered raptors, methods for increasing the population of North American raptors, and various methods of aiding raptor conservation efforts.
