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 Gatherings of Angels written by Kenneth P. Able and published by Cornell University Press. This book was released on 1999 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The migration of birds has forever amazed and confounded onlookers. How do birds find their way to their destinations? How do they withstand the dangers and rigors of long-distance flight? The survival of migrant birds is increasingly threatened by environmental degradation and manmade hazards; their protection is more critical than ever. Gatherings of Angels offers first-hand accounts by leading experts who convey the beauty and excitement of migration while communicating important messages about avian conservation. The book features twenty-four pages of stunning color photographs with additional black-and-white photographs throughout.Two chapters of background information on migration precede chapters that focus on different species or groups of birds and the localities essential to their survival--from the spring flights of songbirds across the Gulf of Mexico to the massing of sandhill cranes on the Platte River. The authors discuss the timing of migrant travel; the routes followed; and the concentration of birds in stop-over sites, locations that must be preserved if they are to have secure resting spots with fresh water and ample food to fuel their journey.
