The analysis of hormones in feces or excrement presented in the first part of this volume is a relatively new noninvasive method for gaining insight into an animal's physiology. Endocrinological cycles of free-living animals can be studied without the stress caused by capture. Hence, this noninvasive technique may be helpful in a wide range of research fields relating to physiology, behavioral ecology, ethnology, and wildlife conservation. The reports presented in the second part of the volume expand the general understanding of migration over long distances. Three key issues in the search for adaptive syndromes are addressed: acquisition and use of endogenous resources, circadian rhythms, and adaptations in metabolism. The papers included in this volume will provide access to techniques and methods that will result in more reliable studies and more useful data. The results of these two meetings are timely and important because environments are rapidly changing and we need the means to study the impact of these changes on the physiology of animals who are responding to these changes.

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.

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, written by a leading researcher in the field, describes the science of bird migration in an accessible way. Not merely detailing the incredible stamina and navigation skills of birds in their seasonal movements, Berthold also discusses recent ideas, hypotheses, experimental results, and methods in this fascinating field, giving a sense of how we know what we know. No other book covers this ground in such a concise text. There are twelve chapters, including information on types of migration, migratory behaviour, physiological adaptations, orientation mechanisms and navigation, and conservation needs of migrants. For birdwatchers and naturalists, as well as professional ornithologists, this book will inspire a new appreciation and understanding of migrating birds.

Bird migration is one of the most astonishing feats in the natural world. Millions of birds migrate, often over very large distances, to benefit from seasonal resource surpluses and to avoid predators and competitors. The aim of this study is to survey the phenomena.
