Hawks At A Distance

"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.

An indispensable guide for hawk watchers, this is a completely new edition of the seminal book that introduced a holistic method for identifying distant birds in flight.

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.

Conservation classic Hawks Aloft chronicles the founding of Hawk Mountain Sanctuary, the world's first refuge for birds of prey. This personal account by the Sanctuary, the world's first refuge for birds of prey. This personal account by the sanctuary's first curator, shares the difficulties and discoveries he and his wife encountered during their first years on the Mountain. Filled with information for the flora, fauna, people, and other natural phenomena of the Hawk Mountain region, this is a lively and sometimes funny account of the sanctuary's early years. Published in co-operation with the Hawk Mountain Sanctuary Association.

Birds of Prey of the West and its companion volume, Birds of Prey of the East, are the most comprehensive and authoritative field guides to North American birds of prey ever published. Written and lavishly illustrated with stunning, lifelike paintings by leading field-guide illustrator, photographer, and author Brian Wheeler, the guides depict an enormous range of variations of age, sex, color, and plumage, and feature a significant amount of plumage data that has never been published before. The painted figures illustrate plumage and species comparisons in a classic field-guide layout. Each species is shown in the same posture and from the same viewpoint, which further assists comparisons. Facing-page text includes quick-reference identification points and brief natural history accounts that incorporate the latest information. The range maps are exceptionally accurate and much larger than those in other guides. They plot the most up-to-date distribution information for each species and include the location of cities for more accurate reference. Finally, the guides feature color habitat photographs next to the maps. The result sets a new standard for guides to North America's birds of prey. Lavishly illustrated with stunning, lifelike paintings Written and illustrated by a leading authority on North American birds of prey Depicts more plumages than any other guide Concise facing-page text includes quick-reference identification points Classic field-guide layout makes comparing species easy Large, accurate range maps include up-to-date distribution information Unique color habitat photographs next to the maps

A visually stunning, comprehensive resource on North America’s birds of prey, from the award-winning birder and author of Gulls Simplified. Always a popular group of birds, raptors symbolize freedom and fierceness, and in Pete Dunne’s definitive guide, these traits are portrayed in hundreds of stunning color photographs showing raptors up close, in flight, and in action—fighting, hunting, and nesting. These gorgeous photographs enhance the comprehensive, authoritative text, which goes far beyond identification to cover raptor ecology, behavior, conservation, and much more. In returning to his forte and his first love, Pete Dunne has crafted a benchmark book on raptors: the first place to turn for any question about these highly popular birds, whether it’s what they eat, where they live, or how they behave. “Birds of Prey is exhaustively researched and complemented by a stunning collection of photos, but the real highlight is…Dunne’s writing. He weaves together personal anecdotes, historical accounts, and technical information to create something greater than the sum of all its parts: a beautiful, authoritative, and engagingly written guide to the natural history of North American hawks.”—David Sibley, author of The Sibley Guide to Birds “Books about raptors used to fall into two major categories: field guides versus nature writing. No more!...Dunne’s new book skillfully conjoins those two genres. Life a good field guide, Birds of Prey is authoritative and utilitarian, and like our finest nature writing, Dunne’s prose is lyrical, sensitive, and full of feeling.”—Ted Floyd, editor, Birding

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.
