The moult strategies of birds are not only of importance in their impact on a species' ecology and energetics, but as a valuable tool for anyone studying the migration and population dynamics of bird species. 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. An appendix gives supplementary information on ageing birds by the degree of pneumatisation of the skull.
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. 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. 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 second part is of particular value to ringers. 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 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. This second edition has been completely updated and revised, with 16 new species accounts added, bringing the total covered to 74.

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. 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. 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.
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 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.
