Right from the start of this century, field observations and the patient ringing of birds have made available a growing mass of data on the breeding and resting areas of migratory species and on the course, period and duration of their seasonal flights. Considered as a whole, this work on migration morphology commands admiration, and when view ed in detail it reveals fascinating insights into the extraordinary naviga tional performances of many bird species, which find their way over enormous distances. Yet only a few dozen physiologists are actively trying to answer the question of how these performances are achieved. Experimental work on migratory birds raises many difficulties, some of them insuperable, so that many researchers carry out their experiments on the homing pigeon, which is constantly motivated by homesickness and ready to display its ability to flyaway home. Many of the problems connected with bird navigation are still un solved, but a rapidly growing body of results is being produced along with a variety of new ideas and approaches. A clear majority of the stu dents of bird navigation met in September 1981 in Tirrenia, a seaside resort on the Tyrrhenian coast, where each of them offered new in sights into his or her recent investigations. Their contributions have been connected in this volume, which provides an up-to-date conspec tus of the stage reached by research in this field.

How migratory birds can navigate home from their wintering grounds to their breeding sites over hundreds and thousands of kilometres has been an admired mystery over more than a century. Profound advances towards a solution of this problem have been achieved with a model bird, the homing pigeon. This monograph summarizes our current knowledge about pigeon homing, about the birds' application of a sun compass and a magnetic compass, of a visual topographical map within a familiar area and -- most surprisingly -- of an olfactory map using atmospheric chemosignals as indicators of position in distant unfamiliar areas.

Have you ever wondered how migratory birds, some weighing less than a paperclip, navigate thousands of miles across continents and oceans, often returning to the same breeding grounds year after year? This book, *Bird Magnetic Navigation*, delves into the fascinating world of avian migration, specifically exploring the intricate mechanisms by which birds utilize Earth's magnetic field as an internal compass. Understanding this "sixth sense" not only reveals fundamental aspects of animal behavior but also has implications for fields ranging from conservation biology to the development of advanced navigational technologies. This book will address key questions, such as pinpointing the specific sensory systems birds use to detect magnetic fields and analyzing the neural pathways involved in processing magnetic information for long-distance navigation. Furthermore, we explore how magnetic navigation interacts with other navigational cues, such as the sun, stars, and landmarks. These topics are crucial because they provide insights into the cognitive and sensory capabilities of birds and highlight the importance of maintaining natural environments vital for their survival. The investigation of bird migration has a rich history, with early ornithologists relying on banding and visual observation to track movements. However, only recently has the technology become available—through techniques like telemetry, sophisticated behavioral experiments, and advanced molecular biology—to probe the underlying mechanisms of magnetic navigation. This book builds upon this foundation, presenting cutting-edge research and synthesizing existing knowledge into a comprehensive overview. The central argument of *Bird Magnetic Navigation* is that avian magnetic navigation is a complex, multi-sensory process involving specialized photoreceptors in the eyes and potentially iron-based receptors in the beak or inner ear, all integrated within a dedicated neural network. The book will demonstrate that the ability to sense and interpret magnetic fields is not merely an innate instinct but a flexible system influenced by genetics and environmental factors, allowing birds to adapt their migratory routes in response to changing conditions. The book is structured to guide the reader from foundational concepts to the latest research findings. We begin by introducing the basics of the Earth's magnetic field and reviewing the history of research in avian migration. Then, we delve into the sensory mechanisms that enable birds to detect magnetic fields, presenting evidence from anatomical, physiological, and behavioral studies. Next, the book examines how birds integrate magnetic information with other cues for orientation and navigation, exploring the cognitive processes involved in making navigational decisions. The book culminates by discussing the challenges facing migratory birds in a rapidly changing world. The evidence presented relies on a wide range of data, including behavioral experiments, physiological recordings, neuroanatomical tracing, and genetic analyses. We will discuss studies involving controlled magnetic field manipulations, lesion experiments targeting specific brain regions, and molecular analyses identifying candidate genes involved in magnetoreception. Original data from field studies tracking bird movements using GPS and other telemetry devices will also be presented. The study of bird magnetic navigation connects to various disciplines, including physics (understanding the geomagnetic field), neurobiology (decoding neural pathways and sensory mechanisms), and ecology (assessing the impact of environmental changes on migratory behavior). These interdisciplinary perspectives enrich our understanding of the complex interplay between birds and their environment. This book adopts a balanced approach, presenting scientific evidence in an accessible manner while acknowledging the uncertainties and debates within the field. The writing style is clear and concise, aiming to inform and engage a broad audience with an interest in animal behavior, ecology, and sensory biology. The target audience primarily includes students, researchers, and professionals in ornithology, ecology, zoology, and neuroscience. Bird enthusiasts, conservationists, and anyone curious about the wonders of the natural world will also find this book accessible and interesting. As a science-focused book, *Bird Magnetic Navigation* adheres to the conventions of presenting well-researched information, supported by empirical evidence and citations. The book acknowledges the complexities of the subject matter and addresses potential limitations in current knowledge. While the book provides a broad overview of avian magnetic navigation, it intentionally focuses on the underlying mechanisms and sensory biology. It does not delve deeply into specific conservation strategies or the detailed ecology of individual migratory species. The knowledge gained from studying bird magnetic navigation has potential real-world applications, including improving GPS technology, developing new methods for wildlife conservation, and informing our understanding of how electromagnetic fields affect living organisms. While the existence of avian magnetic sense is well-established, the exact nature of the sensory receptors and the neural pathways involved remains a subject of ongoing debate. This book presents the different hypotheses and competing theories, critically evaluating the evidence for each.

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.

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.

The German Society of Cybernetics organizes international conferences on selected interdisciplinary topics in regular 3-year intervals. The aim of these meetings is to bring together scientists who work in quite different disciplines, but are confronted with related problems and use the same or similar approaches. The topic of the 1983 conference which was held on March 23-25 at the University of Tiibingen came from a typical field of research in which engineers, biologists, and phYSicists share a common interest. We do not want to discuss here in detail the common principles which are used by nature and by engineers to solve the problems associated with localization and orientation, since the reader will find enough examples in this volume. The question, however, whether the participants of such meetings can really profit from each other, deserves some further consid eration. First, there is the difficulty of finding a common language. This still seems to be a problem, although in some fields the language of engineers and biologists has become very similar over the years, an impression we also gained during the conference. Most of the authors made a great ef fort to use a vocabulary which is understandable to people outside their own field of research, but, admittedly, not all succeeded.

Movement, dispersal, and migration on land, in the air, and in water, are pervading features of animal life. They are performed by a huge variety of organisms, from the smallest protozoans to the largest whales, and can extend over widely different distance scales, from the microscopic to global. Integrating the study of movement, dispersal, and migration is crucial for a detailed understanding of the spatial scale of adaptation, and for analysing the consequences of landscape and climate change as well as of invasive species. This novel book adopts a broad, cross-taxonomic approach to animal movement across both temporal and spatial scales, addressing how and why animals move, and in what ways they differ in their locomotion and navigation performance. Written by an integrated team of leading researchers, the book synthesizes our current knowledge of the genetics of movement, including gene flow and local adaptations, whilst providing a future perspective on how patterns of animal migration may change over time together with their potential evolutionary consequences. Novel technologies for tracking the movement of organisms across scales are also discussed, ranging from satellite devices for tracking global migrations to nanotechnology that can follow animals only a millimetre in size. Animal Movement Across Scales is particularly suitable for graduate level students taking courses in spatial animal ecology, animal migration, and 'movement ecology', as well as providing a source of fresh ideas and opinions for those already active within the field. It will also be of interest and use to a broader audience of professional biologists interested in animal movements and migrations.
