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
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 ...
Moult and Ageing of European Passerines
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, an...
Während Corona um die Welt. Life is a Story - story.one
Ich war 20 Jahre alt, hatte meinen Schulabschluss in der Tasche und wollte endlich los in die große weite Welt. Wäre da nur nicht Corona gewesen. In diesem Buch erzähle ich dir, wie ich trotz anhaltender Pandemie in 522 Tagen eine Grand Tour zu den schönsten Plätzen dieser Erde unternommen habe. Warum lebte ich hierfür neun Monate im Dschungel in Costa Rica? Was hat eine Ausbildung zum Barkeeper in Südafrika mit einem Internat in Guatemala zu tun? Welche Rolle spielt das weltbeste Kreuzfahrtschiff in all dem? Wie kam es dazu, dass ich auf drei verschiedenen Kontinenten innerhalb von zwei Monaten vier Wochen in Quarantäne war? Du wirst erfahren, wie ich durch all dies zu mir fand und lernte, was wirklich wichtig ist. Reise mit mir literarisch durch Mittelamerika und um die Welt. Der Autor erklärt sich bereit, jeweils 10 % seines Honorars an das Aufforstungsprojekt der Tropenstation La Gamba in Costa Rica sowie an das Wohn- und Bildungsheim ASOL in Guatemala Stadt zu spenden.

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 behaviour 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
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 ...
