There are forty species of hawks in North America, including vultures, the California condor, and the bald eagle, our national bird. Heintzelman'smonumental study is a comprehensive survey of what we know about the migrations ofthese magnificent birds in North America, Central America, and the West Indies.After a general introduction on migration season, speeds, and methodology, elevendetailed chapters survey migration routes and statistics in all the followingregions: eastern and western Canada, the Great Lakes area, New England, the MiddleAtlantic states, southern Appalachia, the Gulf Coast, the Central states, Westernstates, Central America, and the West Indies. Subsequent chapters deal with theinfluence of weather systems and local weather variables, updrafts, thermals, altitudes and the daily rhythm of migrations, the influence of age and geography, and the role of hawk counts as indices to population trends.

Hawks fly at very high altitudes, sometimes over water, and thus their flight behavior and migration patterns are extremely difficult to study. Now, based on nearly ten years of research, this book provides the most complete analysis to date of how hawks migrate. Paul Kerlinger has employed both direct observations and radar techniques to obtain a much more accurate understanding of the migratory behavior of hawks and the "decisions" they make in flight. And, he has integrated data on the flight behavior of raptors in general with information about their ecology, physiology, evolution, and nonmigratory behavior. Kerlinger begins with an overview, discussing ecology and geography, research methods, natural history, and evolution, and atmospheric structure. He then addresses specific aspects of flight behavior: aerodynamics, morphology, mechanics, direction, altitude, flocking, water crossing, speed selection, daily distance traveled, and flight strategies. Kerlinger describes each aspect of behavior quantitatively, testing mechanistic hypotheses. In conclusion, he examines how migrants integrate these behavioral components. Throughout the text he draws comparisons between the migratory flight behavior of hawks and that of other taxa. By means of such comparisons, researchers can gain insight into the selective pressures that shape the behavior of migrant species.
