Considers all aspects of research since experimentation began on the subject in 1925
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.
Ten years have passed since the first edition of this book. During that time the field of bird migration has experienced many advances which are reflected in this second edition. No other book exists to bring together the vast amount of information currently available on the subject of bird migration. Includes discussion of evolution and history of bird migration, physiology, orientation mechanisms and threats to migrations and is accessible to experts as well as amateurs.
The Migration Ecology of Birds, Second Edition covers all aspects of this absorbing subject, including migratory processes, problems of navigation and vagrancy, timing and physiological control of migration, large-scale movement patterns, the effects of recent climate change, the problems that migrants face, and the factors that limit their populations. This book provides a thorough and in-depth review of the state of the science, with the text supplemented by abundant tables, maps and diagrams. Written by a world-renowned avian ecology and migration researcher, this book reveals the extraordinary adaptability of birds to the variable and changing conditions across the globe. This book represents the most updated and detailed review of bird migration, its evolution, ecology and bird physiology. Written in a clear and readable style, it will appeal not only to migration researchers in the field and ornithologists, but to anyone with an interest in this fascinating subject. - Features updated and trending ecological aspects, including various types of bird movements, dispersal and nomadism, and how they relate to food supplies and other external conditions - Contains numerous tables, maps, diagrams, a glossary, and a bibliography of more than 3,000 up-to-date references - Written by an active researcher with a distinguished career in avian ecology, including migration research
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.
Scott Weidensaul follows hawks over the Mexican coastal plains, Bar-tailed Godwits that hitchhike on gale winds 7,000 miles nonstop across the Pacific from Alaska to New Zealand, and the Myriad Songbirds whose numbers have dwindled so dramatically in recent years.
Birds.
The first reference to demonstrate how birds survive the high-altitude Central Asian Flyway and the threats to this unique migration.
Migration Hotspots brings the spectacle and excitement of amazing bird migrations to the general reader. Each spring and autumn hundreds of millions of birds - wildfowl, shorebirds, raptors, and passerines - migrate between higher and lower latitudes, or in some cases between high latitudes in the northern hemisphere and high latitudes in the southern hemisphere. In a handful of places around the world, a combination of geography, topography and climate combine to funnel migrant birds into narrow fronts, leading to migration hotspots, places where, for a few days each year, birds seem to be everywhere. The sight of thousands upon thousands of birds is one of nature's greatest wildlife spectacles. Migration Hotspots takes a look at 30 of the locations where the planet's most dramatic bird migration can be witnessed, from raptor bottlenecks such as Veracruz (Mexico) and the Strait of Messina (Italy) to places like Point Pelée (Canada) and Beidaihe (China) where spectacular falls of songbirds can take place. And from wetlands where huge numbers of waders stop over each spring and autumn to the great rarity islands of Scilly and Heligoland. The book covers each of the world's major avian flyways and features stunning photography throughout. The geographical reasons for the importance of each hotspot are explained, with a summary of the different birds that pass through and the best times of year to see them, and an introductory chapter summarises birds' migration strategies.
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.
