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.

A lyrical celebration of the fascinating ways birds move through the air. This collection of captivating poems celebrates the distinctive movements of twelve birds in flight and the special words associated with those movements, from geese that skein and puffins that wheel, to crows that mob and starlings that murmurate. The evocative language conveys the beauty of these animals and describes how each one makes its own unmistakable way in the world. An informational sidebar complements each poem, describing the reasons behind the bird’s unique way of flying. Children will be captivated by the magnificence of these birds in flight.

The New York Times bestselling author revisits his signature world of Midkemia in this first book in a new trilogy that ushers in the third, and most dramatic, Riftwar yet: the Darkwar Flight of Nighthawks picks up two years after Exile’s Return as Pug, the powerful sorcerer, awakens from a nightmare that portends destruction for all of Midkemia. Disturbed by his dream, Pug calls for a convening of the Conclave of Shadows. Meanwhile, in a small town on the other side of Midkemia, two young brothers are coming of age. As they travel away from home, towards apprenticeships and adulthood, the boys are attacked by bandits and mistakenly transported to Sorcerer’s Isle, the home of the Conclave of Shadows. Though they are untrained and unready, the brothers will join the powerful, mysterious Conclave to confront Midkemia’s most looming evil yet—the Nighthawks, assassins feared throughout the centuries. And Pug will face his old nemesis, the evil wizard formerly known as Sidi, now Leso Varen, in a confrontation with everything at stake: his honor, his life, and the future of Midkemia.

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.

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.

Birds of prey can be particularly difficult to track for a variety of reasons: - Nocturnal behavior - Remote habitats - Migratory patterns - Swift flight speeds Hawks and Owls depicts both the subtle differences and rich diversity among these awe-inspiring birds. With crisp, clean photographs and precise identification notes, this guide makes quick and accurate classifications easier. The families of birds includes: New world vultures Osprey, kites, eagles, hawks and allies Caracara and falcons Barn and bay owls Typical owls The information on each species is concisely organized and includes the differences between male and female, seasonal and immature plumage, morphs and distinctive markings. Color pictures and range maps accompany the text. The 180 photographs from award-winning photographers show these birds in their natural environments through the seasons. Comparison pages group similar-looking birds on a single page for quick reference. Hawks and Owls is a sturdy, pocket-sized field guide that will be indispensable to naturalists, students and birders at all levels of experience, from Florida to Ontario.

Discusses the evolution, biology, life cycle, and social and mating behavior of hawks and falcons.
