Available in PDF, EPUB and Kindle. Book excerpt: Puluwat Atoll in Micronesia, with a population of only a few hundred proud seafaring people, can fulfill anyone's romantic daydream of the South Seas. Thomas Gladwin has written a beautiful and perceptive book which describes the complex navigational systems of the Puluwat natives, yet has done so principally to provide new insights into the effects of poverty in Western cultures.The cognitive system which enables the Puluwatans to sail their canoes without instruments over trackless expanses of the Pacific Ocean is sophisticated and complex, yet the Puluwat native would score low on a standardized intelligence test. The author relates this discrepancy between performance and measured abilities to the educational problems of disadvantaged children. He presents his arguments simply and clearly, with sensitive and detailed descriptions and many excellent illustrations. His book will appeal to anthropologists, psychologists, and sailing enthusiasts alike.

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.

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.

Book excerpt: WINNER OF THE SILVER MEDAL IN THE ANIMAL & NATURE CATEGORY OF THE NAUTILUS AWARDS 2022 Flight has fascinated humans since we first looked into the sky and saw birds on the wing, and no flights are more fascinating than the extraordinary migrations birds make every day, week, month, and season of the year. Migration explores how birds make these incredible expeditions. From first preparing to migrate, to the different types of migration and the compelling reasons why it is a must. From the high-flying adventures of bar-headed geese that soar above the Himalayan Mountains and the long-distance endurance of Arctic terns that travel from pole-to-pole, birds of all families, from vast seasonal migrators to the more casual nomad, will be explored. As readers migrate through the book’s pages, they will also discover avian navigation, curious routes, the hazards of the journey, and why, occasionally, birds end up far from their original destination. Beautifully illustrated, this book will debunk the most outrageous myths about migration as it thoroughly travels the globe exploring the epic journeys these incredible birds make.

Book excerpt: A fascinating and nuanced exploration of why, how, and which birds migrate. Bird migration captivates the human imagination, yet for most of us, key aspects of the phenomenon remain a mystery. How do birds sense the ideal moment to take wing, and once the epic journey has begun, how do they find their distant destinations? Fresh insights about avian movements are still constantly emerging, powered by new tools like molecular genetics and transmitter miniaturization. In this book, renowned ornithologist and author John H. Rappole reveals intriguing results of recent scientific studies on migration, explaining their importance for birders, nature lovers, and researchers alike. Debunking misconceptions about the lives of birds that have persisted for thousands of years, Rappole explores unexpected causes and previously misunderstood aspects of the annual migration cycle. From the role of migrating birds in zoonotic disease transmission to climate change's impact on migration patterns, Rappole tackles crucial questions and ensures that readers come away with a new understanding of why and how birds migrate.

Book excerpt: A report is presented on data taken with both wild fowl and Army homing pigeons trained at State College, Pennsylvania, with the object of seeking information on new mechanisms of bird navigation or to get data which will tend to support or refute existing theories. Another report is presented on data taken exclusively with wild fowl to find new leads regarding possible navigating mechanisms and indications of navigational or non-navigational tendencies with birds released in unfamiliar territory at great distances from the navigational training area. The design the experiment involved taking the birds well away from their home areas and giving no special consideration to any known theory of bird navigation. (Author).

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.
