A brand-new, completely revised second edition of Jenni and Winkler's classic guide, updated and improved for the next generation of ringers and professional ornithologists. The moult strategies of birds exert an important influence on their behaviour and energetics, and also provide the basis of valuable tools for study. A proper understanding of how feathers are replaced and the precise differences in the appearance of the various feather generations can allow ringers, scientists and keen birdwatchers to age individual birds, and to distinguish between first-year and adult birds. Understanding the moult strategy of a species also provides insights into its general and migration ecology, and allows detailed studies of many aspects of its population dynamics. Lukas Jenni and Raffael Winkler have studied moult across a wide range of bird species for decades, and in this book bring their observations together to produce a valuable reference for both professional ornithologists and bird ringers. This second edition has been completely updated and revised, with 16 new species accounts added, bringing the total covered to 74. The first part of the book provides an up-to-date summary of the moult strategies and moult sequences of European passerines, and discusses the ecological consequences of moult. Throughout the book, the authors draw on the enormous amount of data on moult that they have collected over 40 years of study and which, combined with data from the literature, allow them to present a thorough synthesis of the subject. The second part is of particular value to ringers. Following a general introduction to ageing, detailed moult profiles are given for 74 European passerine species, illustrating all of the major moult strategies and including useful summary statistics, schematic diagrams of the extent of moult and indications of the variation within each species. The main moult strategies are illustrated with schematic graphs, and the moult strategies and extent of moult of every European passerine species are summarised in tabular form. The crowning feature of this book is its collection of more than 600 full-colour photographs of extended wings, which show the entire range of moult patterns and plumage-ageing criteria. An appendix gives supplementary information on ageing birds by the degree of pneumatisation of the skull. Large in format, packed with high-quality photography and lavish in production specifications, this second edition of Moult and Ageing in European Passerines is both a major reference for ornithologists, zoologists, bird ringers and dedicated birdwatchers, and a work of great scholarship and beauty.

The first comprehensive review of all aspects of the biology of moult, drawing information from across the literature and in all birds, from penguins to passerines. Feathers are amazing structures. All birds need to renew their feathers periodically, in a process called moult. Because feathers can only be renewed as a whole, all functions of the plumage are impaired during moult, and so this process has a crucial impact on most aspects of a bird’s life. Therefore the period of moult is one of the most important recurring annual events in the life of a bird, together with reproduction and, for many, migration. Given the major impacts of this process on birds, moult remains a sorely neglected field of ornithological research. This book, written by the internationally renowned ornithologists Lukas Jenni and Raffael Winkler, seeks to redress this. Early chapters provide an overview of the functions of plumage. Later, it moves on to subjects such as plumage maintenance and feather wear, the two main functions of moult; feather-growth, the physiology, energetics and control of moult; and how moult affects plumage quality, structural quality and coloration, and the consequences of this for the bird. The book concludes with a review of the various solutions developed by birds to fit moult into their annual cycle. Complementary to the magnificent Moult and Ageing in European Passerines by the same authors and packed with color photography throughout, The Biology of Moult in Birds is the first comprehensive review of all aspects of the biology of moult, drawing information from across the literature and in all birds, from penguins to passerines.

Although scientists have discovered many fundamental physiological and behavioral mechanisms that comprise the stress response, most of current knowledge is based on laboratory experiments using domesticated or captive animals. Scientists are only beginning, however, to understand how stress impacts wild animals - by studying the nature of the stressful stimuli that animals in their natural environments have adapted to for survival, and what the mechanisms that allow that survival might be. This book summarizes, for the first time, several decades of work on understanding stress in natural contexts. The aim is two-fold. The first goal of this work is to place modern stress research into an evolutionary context. The stress response clearly did not evolve to cause disease, so that studying how animals use the stress response to survive in the wild should provide insight into why mechanisms evolved the way that they did. The second goal is to provide predictions on how wild animals might cope with the Anthropocene, the current period of Earth's history characterized by the massive human remodeling of habitats on a global scale. Conservation of species will rely upon how wild animals use their stress response to successfully cope with human-created stressors.

Wagtails are noted for their bold plumage patterns and extensive racial variation. Pipits are a large and difficult group which invariably causes vexation to birders on both sides of the Atlantic. This guide covers the 26 species of northern hemisphere pipits and wagtails in detail. It treats identification in the field and in the hand, and includes colour plates, detailed distribution maps and sonograms of songs and calls.

The aim of this book is to outline the main methods and techniques available to ornithologists. A general shortage of information about available techniques is greatly hindering progress in avian ecology and conservation. Currently this sort of information is disparate and difficult to locate with much of it widely dispersed in books, journals and grey literature. Sutherland and his editorial team bring together in a single authoritative source all the ornithological techniques the avian community will ever need. For use by graduate students, researchers and practising conservationists worldwide. Bird Ecology and Conservation is the first title in a new series of practical handbooks which include titles focusing on specific taxonomic groups as well as those describing broader themes and subjects. The series editor is William J Sutherland.

The Avian Migrant

The purpose of migration, regardless of the distance involved, is to exploit two or more environments suitable for survival or reproduction over time, usually on a seasonal basis. Yet individual organisms can practice the phenomenon differently, and birds deploy unique patterns of movement over particular segments of time. Incorporating the latest research on bird migration, this concise, critical assessment offers contemporary readers a firm grasp of what defines an avian migrant, how the organism came to be, what is known about its behavior, and how we can resolve its enduring mysteries. John H. Rappole's sophisticated survey of field data clarifies key ecological, biological, physiological, navigational, and evolutionary concerns. He begins with the very first migrants, who traded a home environment of greater stability for one of greater seasonality, and uses the structure of the annual cycle to examine the difference between migratory birds and their resident counterparts. He ultimately connects these differences to evolutionary milestones that have shaped a migrant lifestyle through natural selection. Rather than catalogue and describe various aspects of bird migration, Rappole considers how the avian migrant fits within a larger ecological frame, enabling a richer understanding of the phenomenon and its critical role in sustaining a hospitable and productive environment. Rappole concludes with a focus on population biology and conservation across time periods, considering the link between bird migration and the spread of disease among birds and humans, and the effects of global warming on migrant breeding ranges, reaction norms, and macroecology.
