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: Raptors are formally classified into five families and include birds—such as eagles, ospreys, kites, true hawks, buzzards, harriers, vultures, and falcons—that are familiar and recognized by many observers. These diurnal birds of prey are found on every continent except Antarctica and can thrive in seemingly inhospitable spots such as deserts and the tundra. They have powerful talons and hooked beaks for cutting and tearing meat, and keen binocular vision to aid in their hunting prowess. Because of their large size, distinctive feeding habits, and long-distance flight patterns, raptors intrigue humans and have been the subject of much general interest as well as extensive scientific research. Keith L. Bildstein has watched and studied raptors on five continents and is well prepared to explain their critical importance, not only as ecological entities but also as inspirational tokens across natural and human-dominated landscapes. His book offers a comprehensive and accessible account of raptors, including their evolutionary history, their relationships to other groups of birds, their sensory abilities, their general natural history, their breeding ecology and feeding behavior, and threats to their survival in a human-dominated world. Biologically sound but readable, Raptors is a nontechnical overview of this captivating group. It will allow naturalists, birders, hawk-watchers, science educators, schoolchildren, and the general public, along with new students in the field of raptor biology, to understand and appreciate these birds, and in so doing better protect them.

Available in PDF, EPUB and Kindle. Book excerpt: E. GWINNER! The phenomenon of bird migration with its large scale dimensions has attracted the attention of naturalists for centuries. Worldwide billions of birds leave their breeding grounds every autumn to migrate to areas with seasonally more favor able conditions. Many of these migrants travel only over a few hundred kilo meters but others cover distances equivalent to the circumference of the earth. Among these long-distance migrants are several billion birds that invade Africa every autumn from their West and Central Palaearctic breeding areas. In the Americas and in Asia the scope of bird migration is of a similar magnitude. Just as impressive as the numbers of birds are their achievements. They have to cope with the enormous energetic costs of long-distance flying. particularly while crossing oceans and deserts that do not allow replenishment of depleted fat reserves. They have to appropriately time the onset and end of migrations. both on a daily and annual basis. And finally. they have to orient their migratory movements in space to reach their species- or population-specific wintering and breeding grounds, irrespective of the variable climatic conditions along their migratory routes.
