Moult and Ageing of European Passerines
THE BTO/BRITISH BIRDS BOOK OF THE YEAR 2020 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 insight...
Moult and Ageing of European Passerines
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. A proper understanding of how feathers are replaced, and the precise differences in appearance of the various feather generations, can allow ringers, scientists and the keen birdwatcher to age first-year and adult birds and to detect the moult strategy of the bird in question. Lukas Jenni and Raffael Winkler have combined these themes and produced a book which will be valuable both to the professional ornithologist and the bird ringer. The first part gives an up to date summary of the m...
The Biology of Moult in Birds
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 ...

Urban Peregrines
The Peregrine, the fastest bird in the world, has made a remarkable recovery over the past 30 years. As the species re-establishes itself around the world it is becoming a familiar sight in towns and cities. This beautifully illustrated book is the first in-depth focus on the lives of Peregrines in towns and cities. In words and stunning photographs, Ed Drewitt reveals the latest information on Peregrine behavior including how they are adapting to, and taking advantage of, the urban environment. The book is also a how-to-guide, with information on finding peregrines, studying their diet, ringing individuals for research, putting up nest boxes and enabling people to learn more about them through public viewing points or web cameras. Ed also discusses what makes a Peregrine urban, their contemporary relationship with people, and helps dispel some myths and reveal some truths about this agile predator.

The Biology of Moult in Birds
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.

Molt in North American Birds
A comprehensive examination of the molt processes (feather growth) of different species of birds, one of the most important and fundamental processes in the life history of any bird.
