Download or read book Birds of Passage written by Michael J. Piore and published by Cambridge University Press. This book was released on 1979 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birds of Passage presents an unorthodox analysis of migration ion to urban industrial societies from underdeveloped rual areas. It argues that such migrations are a continuing feature of industrial societies and that they are generated by forces inherent in the nature of industrial economies. It explains why conventional economic theory finds such migrations so difficult to comprehend, and challenges a set of older assumptions that supported the view that these migrations were beneficial to both sending and receiving societies. Professor Piore seriously questions whether migration actually relieves population pressure and rural unemployment, and whether it develops skills necessary for the emergence of an industrial labour force in the home country. Furthermore, he criticizes the notion that in the long run migrant labour complements native labour. On the basis of this critique, he develops an alternative theory of the nature of the migration process.

Download or read book Bird Migration written by Eberhard Gwinner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 436 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological biological observation station in the world (see first chapter "In Memory of Vogelwarte Rossitten"). This area later received enormous impetus when ex perimental research on the subject was begun: the large-scale bird-ringing experiment initiated in Rossitten in 1903 by Johannes Thienemann (who was inspired by the pioneering studies of C. C. M. Mortensen), the experiments on photoperiodicity carried out by William Rowan in the 1920s in Canada and retention and release experiments performed by Thienemann in the 1930s in Rossitten, the first experimental study on the orientation of migratory birds. After the Second World War, migration research, while continuing in the previous areas, also expanded into new directions such as radar ornithology, ecophysiology and hormonal control mechanisms, studies of evolution, ge netics, telemetry and others.

This book was released on 2021-03-30 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: New York Times Bestseller Finalist for the Los Angeles Times Book Prize A Library Journal Best Science and Technology Book of the Year An exhilarating exploration of the science and wonder of global bird migration. In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we’ve learned of these key migrations—how billions of birds circumnavigate the globe, flying tens of thousands of miles between hemispheres on an annual basis—is nothing short of extraordinary. Bird migration entails almost unfathomable endurance, like a sparrow-sized sandpiper that will fly nonstop from Canada to Venezuela—the equivalent of running 126 consecutive marathons without food, water, or rest—avoiding dehydration by "drinking" moisture from its own muscles and organs, while orienting itself using the earth’s magnetic field through a form of quantum entanglement that made Einstein queasy. Crossing the Pacific Ocean in nine days of nonstop flight, as some birds do, leaves little time for sleep, but migrants can put half their brains to sleep for a few seconds at a time, alternating sides—and their reaction time actually improves. These and other revelations convey both the wonder of bird migration and its global sweep, from the mudflats of the Yellow Sea in China to the remote mountains of northeastern India to the dusty hills of southern Cyprus. This breathtaking work of nature writing from Pulitzer Prize finalist Scott Weidensaul also introduces readers to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges. Drawing on his own extensive fieldwork, in A World on the Wing Weidensaul unveils with dazzling prose the miracle of nature taking place over our heads.

Download or read book The Man Who Saved the Whooping Crane written by Kathleen Kaska and published by University Press of Florida. This book was released on 2012-09-16 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of people know a little bit about efforts to save the whooping crane, thanks to the movie Fly Away Home and annual news stories about ultralight planes leading migratory flocks. But few realize that in the spring of 1941, the population of these magnificent birds--pure white with black wingtips, standing five feet tall with a seven-foot wingspan--had reached an all-time low of fifteen. Written off as a species destined for extinction, the whooping crane has made a slow but unbelievable comeback over the last seven decades. This recovery would have been impossible if not for the efforts of Robert Porter Allen, an ornithologist with the National Audubon Society, whose courageous eight-year crusade to find the only remaining whooping crane nesting site in North America garnered nationwide media coverage. His search and his impassioned lectures about overdevelopment, habitat loss, and unregulated hunting triggered a media blitz that had thousands of citizens on the lookout for the birds during their migratory trips. Allen's tireless efforts changed the course of U.S. environmental history and helped lead to the passage of the Endangered Species Act in 1973. Though few people remember him today, his life reads like an Indiana Jones story, full of danger and adventure, failure and success. His amazing story deserves to be told.

Download or read book A Walk Across America written by Peter Jenkins and published by Harper Collins. This book was released on 2001-09-18 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty-five years ago, a disillusioned young man set out on a walk across America. This is the book he wrote about that journey -- a classic account of the reawakening of his faith in himself and his country. "I started out searching for myself and my country," Peter Jenkins writes, "and found both." In this timeless classic, Jenkins describes how disillusionment with society in the 1970s drove him out onto the road on a walk across America. His experiences remain as sharp and telling today as they were twenty-five years ago -- from the timeless secrets of life, learned from a mountain-dwelling hermit, to the stir he caused by staying with a black family in North Carolina, to his hours of intense labor in Southern mills. Many, many miles later, he learned lessons about his country and himself that resonate to this day -- and will inspire a new generation to get out, hit the road and explore.
Download or read book A Season on the Wind written by Kenn Kaufman and published by HarperCollins. This book was released on 2019-04-02 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: A close look at one season in one key site that reveals the amazing science and magic of spring bird migration, and the perils of human encroachment. Every spring, billions of birds sweep north, driven by ancient instincts to return to their breeding grounds. This vast parade often goes unnoticed, except in a few places where these small travelers concentrate in large numbers. One such place is along Lake Erie in northwestern Ohio. There, the peak of spring migration is so spectacular that it attracts bird watchers from around the globe, culminating in one of the world’s biggest birding festivals. Millions of winged migrants pass through the region, some traveling thousands of miles, performing epic feats of endurance and navigating with stunning accuracy. Now climate change threatens to disrupt patterns of migration and the delicate balance between birds, seasons, and habitats. But wind farms—popular as green energy sources—can be disastrous for birds if built in the wrong places. This is a fascinating and urgent study of the complex issues that affect bird migration.
