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.

Available in PDF, EPUB and Kindle. Book excerpt: 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
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 Tundra Plovers written by Des Thompson and published by Bloomsbury Publishing. This book was released on 2011-11-30 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are four species of tundra plover: the Grey Plover, and the Eurasian, Pacific, and American golden plovers. They breed only in the northern hemisphere, principally on tundra, and migrate far south to coastal mudflats, saltings and agricultural landscapes. They have attracted avid interest from birdwatchers and researchers worldwide, not least the authors who have studied all four species. The Eurasian Golden Plover has a special claim to fame as questions over its flight speed first prompted the compilation of the world bestseller the Guinness Book of Records! This ground-breaking book on shorebirds (waders) examines the taxonomy, appearance, behaviour, ecology and conservation of Golden and Grey plovers, and compares and contrasts their natural history and biogeography. There are detailed accounts on all aspects of their lifestyle including feeding, mating, parental care, moults, migration and avoidance of predators. The personal touches in this book add immensely to its value, not least the authors' first hand experiences of the birds and their haunts. Most of their work presented here has not been published before, adding to the significance of this highly original book. Long-awaited considerations of differences in plumage, vocalisations, habitat use, breeding, movements and food are included. The links between phylogeny, biogeography and behaviour are bound to excite interest. The comparative approach is highly detailed and refreshing, and marks the book as a classic. Ingvar Byrkjedal has also contributed all of the wonderful colour and line illustrations. Over fifty-five photographs, over one hundred and twenty tables and figures, and many other embellishments complete this definitive book.

Download or read book Birds of the Strait of Gibraltar written by Clive Finlayson and published by A&C Black. This book was released on 2010-09-30 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clive Finlayson, a native of the Rock and a trained ornithologist, presents a fascinating account of this region and its resident and transitory bird life. The Strait of Gibraltar is famous as a major point of passage for Palaearctic birds migrating between their European breeding grounds and their winter quarters in Africa. The first chapter of the book describes the area, which broadly defined includes the Coto Donana in the north and the Merja Zerga in the south, and the geographic and climatological characteristics which make it a suitable crossing place. In scope this book goes beyond the strict definition of the Strait and, following Irby's 19th Century work, examines the rich area where Europe meets Africa. The chapters which follow describe in detail the migration patterns of the principal passage species including their origins, destinations and overall numbers, showing how the precise conditions of weather and visibility affect the specific choice of route and timing of the crossing. The breeding and wintering bird communities are then considered and the ornithology of the entire region summarized. Whether or not you have ever witnessed the thousands of raptors, storks and other birds that may make this legendary crossing in a single day, this book will conjure the spirit of this extraordinary place. Delightful illustrations by lan Willis complete an important and entertaining book.
