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 Moult and Ageing of European Passerines 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 Moult and Ageing of European Passerines provides an up-to-date summary of the moult strategies and moult sequences of European passerines, and discusses the ecological consequences of moult. Throughout Moult and Ageing of European Passerines, 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 Moult and Ageing of European Passerines 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 of European Passerines is both a major reference for ornithologists, zoologists, bird ringers and dedicated birdwatchers, and a work of great scholarship and beauty.

Lukas Jenni was a volunteer at the Swiss Ornithological Institute while studying zoology, botany, geology and chemistry at Basel University. His interest in moult and ageing arose while working with Raffael Winkler. His main research interests are in ecology and the physiology of bird migration, as well as moult biology.
Raffael Winkler graduated with a PhD thesis on the pneumatization of the skull roof in birds. In 1980 he was elected curator of the bird collection at the Natural History Museum, Basel. Since then, he has edited the Avifauna of Switzerland and carried on the Museum's own tradition in moult research.
– The BB/BTO Best Bird Book of the Year, 2020
"[...] Those who use the first edition will still want this new version because good as the first edition was, this is even better. [...] Accompanying [each account] is a series of digital colour photographs illustrating the various stages of moult. As one might expect in a work of this kind where small differences in colour matter, these are of the highest standard. Still photographs can never quite replace having the actual feather in one's hand – where small changes in angle can help to see differences. Nevertheless, on a small sample examined, the plates match the birds exceedingly well and almost all are of sufficiently high quality to clearly display the differences described in the text. [...] "

"The second edition of Jenni & Winkler is superb. It replaces the first edition as one of my favourite publications, and one that will continue to be well used. It is not cheap, but if you have even the slightest interest in moult or ageing, it really is a must-have [...]"
– Stephen Menzie, British Birds 113, May 2020
"[...] The guide distils decades' worth of personal ringing data and is an excellent reference work for any ringer not fortunate enough to own the first edition; and, even then, there are good reasons to upgrade. For those who have started ringing more recently or have an interest in passerine moult, then this outstanding book comes highly commended."
