Book Description
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

Book Description
A splendid and luminous celebration of one of nature’s most perfect and mysterious creatures—the hawk—from the New York Times bestselling author of the “astoundingly beautiful” (NPR) The Soul of an Octopus. When Sy Montgomery went to spend a day at falconer Nancy Cowan’s farm, home to a dozen magnificent birds of prey, it was the start of a deep love affair. Nancy allowed her to work with Jazz, a feisty, four-year-old, female Harris’s hawk with a wingspan of more than four feet. Not a pet, Jazz was a fierce predator with talons that could pierce skin and bone and yet, she was willing to work with a human to hunt. From the first moment Jazz swept down from a tree and landed on Sy’s leather gloved fist, Sy fell under the hawk’s magnetic spell. Over the next few years, Sy spent more time with these magnificent creatures, getting to know their extraordinary abilities and instincts. They are deeply emotional animals, quick to show anger and frustration, and can hold a grudge for years. But they are also loyal and intensely aware of their surroundings. In this mesmerizing account, featuring sixteen pages of gorgeous color photographs, Sy passionately and vividly reveals the wonderous world of hawks and what they can teach us about nature, life, and love.

Book Description
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.
