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
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...
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...
Avian Migration
P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological biological observation station in the world (see first chapter "In M...
Passerine Migration
Most birds cannot cover the distance between their breeding and winter quarters in one hop. They have to make multiple flights alternated with stopovers. Which factors govern the birds’ decisions to stop, to stop for how long, when to resume flight? What is better – to accumulate much fuel and to make long flights for many hundreds of kilometres, or to travel in small steps? Is it necessary to find habitats similar to the breeding ones or other habitats would do? Are long migratory flights indeed so costly energetically as usually assumed? This monograph summarizes our current knowledge on the ecology of songbird migrants during migratory stopovers and on their behaviour.
Comparative Physiology of Fasting, Starvation, and Food Limitation
All animals face the possibility of food limitation and ultimately starvation-induced mortality. This book summarizes state of the art of starvation biology from the ecological causes of food limitation to the physiological and evolutionary consequences of prolonged fasting. It is written for an audience with an understanding of general principles in animal physiology, yet offers a level of analysis and interpretation that will engage seasoned scientists. Each chapter is written by active researchers in the field of comparative physiology and draws on the primary literature of starvation both in nature and the laboratory. The chapters are organized among broad taxonomic categories, such as protists, arthropods, fishes, reptiles, birds, and flying, aquatic, and terrestrial mammals including humans; particularly well-studied animal models, e.g. endotherms are further organized by experimental approaches, such as analyses of blood metabolites, stable isotopes, thermobiology, and modeling of body composition.
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.
Birds and Habitat
The successful conservation of bird species relies upon our understanding of their habitat use and requirements. In the coming decades the importance of such knowledge will only grow as climate change, the development of new energy sources and the needs of a growing human population intensify the, already significant, pressure on the habitats that birds depend on. Drawing on valuable recent advances in our understanding of bird-habitat relationships, this book provides the first major review of avian habitat selection in over twenty years. It offers a synthesis of concepts, patterns and issues that will interest students, researchers and conservation practitioners. Spatial scales ranging from landscape to habitat patch are covered, and examples of responses to habitat change are examined. European landscapes are the main focus, but the book has far wider significance to similar habitats worldwide, with examples and relevant material also drawn from North America and Australia.

Godwits
This highly illustrated book tells the story of the godwits and their migrations - why and how they do it. It follows the birds on their intrepid journeys, examining the places they visit, be it an estuary in northern New Zealand, a mudflat on the Chinese-North Korean border, or a tundra nesting site in Alaska. Keith Woodley, godwit expert and manager of the Miranda Shorebird Centre in New Zealand, details the amazing changes these bird undergo before and during their voyages - from moulting into new plumage, to doubling their weight and shrinking non-essential body organs - as well as their array of innate skills in weather prediction and global navigation, weaving the latest scientific findings into history, literature and folklore. In Godwits the author's eye-witness accounts and meticulous research culminate in a tale of navigation and stunning fortitude that will delight both professional bird watchers and general readers curious to discover more about one of nature's quiet achievers.
