Book Description
An exploration of the causes and patterns of avian vagrancy Avian vagrancy—the appearance of birds outside of their expected habitat—is a phenomenon that has fascinated natural historians for centuries, from Victorian collectors willing to spend fortunes on a rare specimen to today’s bird-chasing “twitchers.” Yet despite the obsessions of countless ornithologists, what do we actually know about the enigma of vagrancy? In Vagrancy in Birds, Alexander Lees and James Gilroy explore the causes, patterns, and processes behind the occurrences of these unique birds. Lees and Gilroy draw on recent research to answer fundamental questions: What causes avian vagrancy? Why do some places attract so many vagrant birds? Why are some species more predisposed to long-range vagrancy than others? The authors present readers with everything known about the subject, and bring together different lines of evidence to make the case for vagrancy as a biological phenomenon with important implications for avian ecology and evolution. Filled with a wealth of photographs, Vagrancy in Birds will fascinate avian enthusiasts everywhere.

Book Description
How birds have evolved and adapted to survive winter Birds in Winter is the first book devoted to the ecology and behavior of birds during this most challenging season. Birds remaining in regions with cold weather must cope with much shorter days to find food and shelter even as they need to avoid predators and stay warm through the long nights, while migrants to the tropics must fit into very different ecosystems and communities of resident birds. Roger Pasquier explores how winter affects birds’ lives all through the year, starting in late summer, when some begin caching food to retrieve months later and others form social groups lasting into the next spring. During winter some birds are already pairing up for the following breeding season, so health through the winter contributes to nesting success. Today, rapidly advancing technologies are enabling scientists to track individual birds through their daily and annual movements at home and across oceans and hemispheres, revealing new and unexpected information about their lives and interactions. But, as Birds in Winter shows, much is visible to any interested observer. Pasquier describes the season’s distinct conservation challenges for birds that winter where they have bred and for migrants to distant regions. Finally, global warming is altering the nature of winter itself. Whether birds that have evolved over millennia to survive this season can now adjust to a rapidly changing climate is a problem all people who enjoy watching them must consider. Filled with elegant line drawings by artist and illustrator Margaret La Farge, Birds in Winter describes how winter influences the lives of birds from the poles to the equator.

Book Description
This classic Poyser title, now in its third revised edition, discusses in depth the various ways in which weather conditions influence bird behaviour. Weather conditions affect food and water availability, decisions about when and how to migrate, timing and success of reproduction, flight style, and physical comfort. Birds display many adaptations in form and behaviour that help them to cope with changing weather conditions, and this fascinating book uses a great variety of examples to explore the subject in depth. The text is enhanced throughout with evocative line drawings, there are many useful tables and figures, and there is also an 8pp colour photograph section.

Book Description
The Birds of Turkey is the first avifauna to document this country's amazing ornithological diversity. Turkey - ornithologically one of the most fascinating countries in the Western Palearctic - lies not only at the crossroads between Europe and Asia, but also at the meeting point of a variety of biomes. The extensive semi-deserts of the Middle East reach their northernmost limit in southeastern Turkey, while the Pontic Mountains, which dominate much of the north of the country, support a principally European fauna, along with near-endemics such as Caucasian Grouse, Green Warbler, Caspian Snowcock and Krüper's Nuthatch. In Central Turkey, huge saline lakes hold colonies of flamingos, pelicans and Pygmy Cormorants, while the surrounding semi-steppe supports populations of Montagu's Harrier, Great Bustard and abundant lakes. The book looks in detail at every species ever reported in the country - breeding birds, passage migrants, winter visitors and vagrants - with a review of status and distribution, accurate distribution maps, and discussions of breeding biology and the latest taxonomic revisions. Introductory chapters provide overviews of Turkey's major biomes and the history or ornithology in the country, and a discussion of future research objections. The book also contains stunning colour photography by a number of leading Turkish ornithologists. Indispensable for anyone interested in the Turkish avifauna, The Birds of Turkey will remain the standard work on this key ornithological region for many years to come.
