Zustand: NEW. xii, 323, col photos + text figs. . HB. NEW. . A completely revised second edition of this 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.

Buch. Zustand: Neu. Neuware - 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 unique to birds and, for a variety of reasons, they need to be renewed periodically as a whole in a process called moult. During this process, all of the functions of plumage are impaired and most aspects of a bird's life are affected. Every moult determines a bird's appearance anew, and restores plumage efficacy for flight and insulation. Moult profoundly affects physiology and the organization of the annual cycle, and it constrains reproduction and migration. Given these major impacts, which are equal to the other annual challenges of reproduction and migration, it is surprising that research on moult has largely been so neglected a subject. Lukas Jenni and Raffael Winkler have brought together the widely scattered results of studies on the processes and consequences of moult in birds. This book opens with an overview of the functions of plumage, and of feather maintenance and feather wear, and then introduces the two functions of moult: replacement of worn feathers and adjustment of plumage characteristics and appearance.The body of the book then examines feather-growth and the physiology, energetics and control of moult, and how various other physiological processes interact with moult and may compensate for its costs. Significantly, the authors explain how variations in moult and feather quality affect a bird's overall plumage quality, and they highlight the resulting consequences in terms of physical performance, appearance and signalling. Finally, there is a review of all the various solutions that birds have developed to fit moult into the annual cycle.This long-awaited book covers for the first time all aspects of the biology of moult and fills an important gap in the literature, completing our understanding of how the most important annual events in a bird's life fit together into a coherent whole. It draws on a wide range of information - from penguins to small passerines, from raptors to wildfowl - to highlight the variety of the subject and to pinpoint the many gaps in our knowledge along with avenues for fruitful further research.
