Download or read book The Migrations of Hawks written by Donald S. Heintzelman and published by . This book was released on 1986-10-22 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are forty species of hawks in North America, including vultures, the California condor, and the bald eagle, our national bird. Heintzelman's monumental study is a comprehensive survey of what we know about the migrations of these magnificent birds in North America, Central America, and the West Indies. After a general introduction on migration season, speeds, and methodology, eleven detailed chapters survey migration routes and statistics in all the following regions: eastern and western Canada, the Great Lakes area, New England, the Middle Atlantic states, southern Appalachia, the Gulf Coast, the Central states, Western states, Central America, and the West Indies. Subsequent chapters deal with the influence 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.

Download or read book Hawks from Every Angle written by Jerry Liguori and published by Princeton University Press. This book was released on 2016-08-10 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identifying hawks in flight is a tricky business. Across North America, tens of thousands of people gather every spring and fall at more than one thousand known hawk migration sites--from New Jersey's Cape May to California's Golden Gate. Yet, as many discover, a standard field guide, with its emphasis on plumage, is often of little help in identifying those raptors soaring, gliding, or flapping far, far away. Hawks from Every Angle takes hawk identification to new heights. It offers a fresh approach that literally looks at the birds from every angle, compares and contrasts deceptively similar species, and provides the pictures (and words) needed for identification in the field. Jerry Liguori pinpoints innovative, field-tested identification traits for each species from the various angles that they are seen. Featuring 339 striking color photos on 68 color plates and 32 black & white photos, Hawks from Every Angle is unique in presenting a host of meticulously crafted pictures for each of the 19 species it covers in detail--the species most common to migration sites throughout the United States and Canada. All aspects of raptor identification are discussed, including plumage, shape, and flight style traits. For all birders who follow hawk migration and have found themselves wondering if the raptor in the sky matches the one in the guide, Hawks from Every Angle--distilling an expert's years of experience for the first time into a comprehensive array of truly useful photos and other pointers for each species--is quite simply a must. Key Features? The essential new approach to identifying hawks in flight Innovative, accurate, and field-tested identification traits for each species 339 color photos on 68 color plates, 32 black & white photos Compares and contrasts species easily confused with one another, and provides the pictures (and words) needed for identification in the field Covers in detail 19 species common to migration sites throughout the North America Discusses light conditions, how molt can alter the shape of a bird, aberrant plumages, and migration seasons and sites User-friendly format

Available in PDF, EPUB and Kindle. Book excerpt: "Hawks at a Distance" is the first volume to focus on distant raptors as they are truly seen in the field. Jerry Liguori, a leading expert on North American raptors, factors in new information and approaches for identifying twenty-nine species of raptor in various lighting situations and settings. The field guide's nineteen full-color portraits, 558 color photos, and 896 black-and-white images portray shapes and plumages for each species from all angles. Useful flight identification criteria are provided and the accompanying text discusses all aspects of in-flight hawk identification, including flight style and behavior. Concentrating on features that are genuinely observable at a distance ..."--Jacket.

Download or read book Flight Strategies of Migrating Hawks written by Paul Kerlinger and published by . This book was released on 1989 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: "More than 75,000 people come to Hawk Mountain each year to experience its majesty, particularly on the mountain's breathtaking North Lookout. That wonderment is captured here in a book that combines new reporting with classic descriptions and a treasury of photographs of the winged visitors that soar by this place in huge numbers. Based on two years of research and reporting, Hawk Mountain describes the wonders of raptors and their migration, showcases the site throughout the year, and offers chapters from celebrated books from the mountain's past, including Hawks Aloft, by the sanctuary's first curator, Maurice Broun. Hawk Mountain also features two illustrations by the noted nature artist Fred Wetzel, who has been associated with the sanctuary for more than 50 years." --Excerpted from book jacket.
