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.

Given their roles in the ecosystem, raptors are widely considered the flagship or umbrella species among birds. Most species undertake a seasonal journey that is impressive because of the length, and the imposing natural barriers such as deserts and seas that they fly over. The migration of birds of prey has unique characteristics in the animal world because of their morphology and flight style. The flying path of Afro-Palearctic migrants between breeding and wintering grounds is determined by several factors such as morphology of the birds, geography, behavioural adaptations. The book analyses the migration patterns of raptors along the Afro-Palearctic migratory system, and summarizes the recent research on these top predator species. Behavioural adaptations such as the importance of social interactions and the modulation of the different flight styles as well as ecological interactions with the encountered environment and weather conditions en route are described in the book. Moreover, the impact of climate change on the migratory behaviour and key conservation issues are discussed. The book provides an overview of the migratory characteristics and flyway patterns of all European raptors species and also some Asian ones. These chapters have been written by some of the most important raptor specialists, giving a complete picture of the different migration strategies on the basis of both traditional methods and new technologies.

"Keith L. Bildstein has studied migrating raptors on four continents and directs the conservation science program at Hawk Mountain Sanctuary, Pennsylvania, the world's first refuge for migratory birds of prey. In this book, he details the stories and successes of twelve of the world's most important raptor-viewing spots, among them Cape May Point, New Jersey; Veracruz, Mexico; Kekoldi, Costa Rica; the Strait of Gibralter, Spain; and Elat, Israel."--BOOK JACKET.

This book is the ultimate flight-identification guide for the raptors of the Western Palaearctic, covering Europe, North Africa, the Middle East (including Arabia) to Central Asia. Raptors are notoriously hard to identify, even if seen well, and represent perhaps the toughest of all ID challenges for birders. This guide provides identification information for all 60 species that regularly occur in the region, to subspecific level. The text covers every plumage and age in detail, with each species account accompanied by a range of photographs covering all the principal plumages. Based on this stunning photographic coverage, most of which has never been published before, this book represents a landmark in bird identification books and a major work for all raptor enthusiasts.

Floating on air currents over rural countryside and open city spaces, the Mississippi Kite presents a familiar sight to many people across the southern United States, although this graceful hawk is not well known by name. This engaging natural history, illustrated with superb color photographs, provides all a bird watcher needs to become acquainted with the kite, its life cycle, and its fascinating history with humans. Under various folk names, including Blue Darter, Grasshopper Hawk, and Mosquito Hawk, the Mississippi Kite ranges throughout the southern United States from the coasts of the Carolinas to the plains of the Southwest. The authors describe all aspects of the kite's life cycle, from breeding and nesting, raising young, and hunting and feeding to the kite's annual winter migration to South America. They also trace its intriguing relationship with humans, from its discovery by Europeans in the nineteenth century to the present day. For bird lovers and ornithologists alike, The Mississippi Kite will be an essential introduction to a bird well worth knowing. A special section on conservation and a selection of references for further reading complement the text.

An investigation into how machines and living creatures fly, and of the similarities between butterflies and Boeings, paper airplanes and plovers. From the smallest gnat to the largest aircraft, all things that fly obey the same aerodynamic principles. In The Simple Science of Flight, Henk Tennekes investigates just how machines and creatures fly: what size wings they need, how much energy is required for their journeys, how they cross deserts and oceans, how they take off, climb, and soar. Fascinated by the similarities between nature and technology, Tennekes offers an introduction to flight that teaches by association. Swans and Boeings differ in numerous ways, but they follow the same aerodynamic principles. Biological evolution and its technical counterpart exhibit exciting parallels. What makes some airplanes successful and others misfits? Why does the Boeing 747 endure but the Concorde now seem a fluke? Tennekes explains the science of flight through comparisons, examples, equations, and anecdotes. The new edition of this popular book has been thoroughly revised and much expanded. Highlights of the new material include a description of the incredible performance of bar-tailed godwits (7,000 miles nonstop from Alaska to New Zealand), an analysis of the convergence of modern jetliners (from both Boeing and Airbus), a discussion of the metabolization of energy featuring Lance Armstrong, a novel treatment of the aerodynamics of drag and trailing vortices, and an emphasis throughout on evolution, in nature and in engineering. Tennekes draws on new evidence on bird migration, new wind-tunnel studies, and data on new airliners. And his analysis of the relative efficiency of planes, trains, and automobiles is newly relevant. (On a cost-per-seat scale, a 747 is more efficient than a passenger car.)
