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
Download or read book Great Possessions written by David Kline and published by Macmillan + ORM. This book was released on 1991-04-01 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Great Possessions is David Kline's classic memoir celebrating his life as an Amish farmer in Southern Ohio. "Infectiously avid, the author shares his knowledge of mushrooming in spring, chopping firewood in fall, maple-sugaring in late winter, bird-watching all year round, and going on walks across the countryside with his children, ``just . . . seeing things.'' His reverence for nature and his deep religious faith are palpable, and he argues convincingly for the ``small-scale diversified farming'' of the Amish, which ultimately gives back to the earth more than it takes." - Publishers Weekly

Download or read book The Great Eagles written by Michael O'Neal Campbell and published by CRC Press. This book was released on 2022-05-19 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the current literature and knowledge on the evolution and ecology of all the birds named as eagles, with particular emphasis on the larger species. It also examines the past and current relations between eagles and people, including habitat change and conservation issues. Eagle ecologies and conservation are currently seriously impacted by human activities such as industrialization, urbanization, pollution, deforestation and hunting. Some eagle species have consequently experienced extreme population changes. There are, however, some positive developments. Eagles have a strong, historic bond with human civilization, due to their status as the world’s most charismatic birds. Conservation policies have also been successful in repopulating some ecosystems with breeding eagles. Therefore, despite the complexity of this relationship, there may yet be hope for this unique species group, frequently rated as the kings of birds, and symbolic of human power, ambition, royalty, nationality, and even concepts of God. It is hoped that this book will contribute to the further understanding of these unique and fantastic birds.
