Description
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.
