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
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.

Book Description
From the award-winning birder and author of Birds of Prey, an authoritative, information-packed guide to distinguishing North American birds. In this book, bursting with more information than any field guide could hold, the well-known author and birder Pete Dunne introduces readers to the “Cape May School of Birding.” It's an approach to identification that gives equal or more weight to a bird's structure and shape and the observer's overall impression (often called GISS, for General Impression of Size and Shape) than to specific field marks. After determining the most likely possibilities by considering such factors as habitat and season, the birder uses characteristics such as size, shape, color, behavior, flight pattern, and vocalizations to identify a bird. The book provides an arsenal of additional hints and helpful clues to guide a birder when, even after a review of a field guide, the identification still hangs in the balance. This supplement to field guides shares the knowledge and skills that expert birders bring to identification challenges. Birding should be an enjoyable pursuit for beginners and experts alike, and Pete Dunne combines a unique playfulness with the work of identification. Readers will delight in his nicknames for birds, from the Grinning Loon and Clearly the Bathtub Duck to Bronx Petrel and Chicken Garnished with a Slice of Mango and a Dollop of Raspberry Sherbet.

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
Birds -- those "upgiven ghosts" who shape our skies -- and their many styles of flying have inspired us for centuries. Tim Dee became enthralled with birds as a young boy, and their allure has informed how he perceives time as well as how he sees the world and his place in it. Compelling and poetic, A Year on the Wing is a month-by-month account of following these magnificent creatures, on land, at sea, and in the air, over the course of one "dew-dipped year." A memoir of the author's life as well as of the birds' migrations, the book draws on memories of forty years of observing birds as Dee explores the ideas and feelings that birds awaken in their flying, breeding, and dying. A Year on the Wing is also a significant chronicle of Dee's rich reading of a gorgeous literary tradition about birds -- from Aristotle to Thomas Hardy, Dante to Pound, Wordsworth to Ted Hughes -- as well as naturalists' writings that train a scientific eye on these elusive creatures. With a poet's marvelous commingling of nature and language, Dee finds meaning and a fascinating beauty in the quiver of a redstart's tail, elegizes the thrilling skydiving stoop of the once-endangered, now resurgent peregrine falcon, and reflects on the nocturnal restlessness of migrant woodcocks that is suggestive of how nature encodes us all. A Year on the Wing brings us as close as possible to birds, as we seek to understand the unique connection between us and them as well as our separation from them and, by extension, our estrangement from all of nature. Watching birds instills a renewed sense of wonder, getting us airborne and expanding our horizons. This vicarious liftoff does us good in a way hard to define but incontestably felt. It also makes us ever aware of our place on the ground. Dee homes in on those moments when the gap narrows between humans and birds, when birds' freedom gives us our own, making our lives more vibrant and alive. The first book from an exciting new literary voice, this beautifully written memoir celebrates birds and the inspiration they provide through their twice-yearly winged migrations.

Book Description
A stunningly illustrated look at the mating and parenting lives of the world's birds Bird Love looks at the extraordinary range of mating systems in the avian world, exploring all the stages from courtship and nest-building to protecting eggs and raising chicks. It delves into the reasons why some species, such as the wattled jacana, rely on males to do all the childcare, while others, such as cuckoos and honeyguides, dump their eggs in the nests of others to raise. For some birds, reciprocal promiscuity pays off: both male and female dunnocks will rear the most chicks by mating with as many partners as possible. For others, long-term monogamy is the only way to ensure their offspring survive. The book explores the wide variety of ways birds make sure they find a mate in the first place, including how many male birds employ elaborate tactics to show how sexy they are. Gathering in leks to display to females, they dance, pose, or parade to sell their suitability as a mate. Other birds attract a partner with their building skills: female bowerbirds rate brains above beauty, so males construct elaborate bowers with twig avenues and cleared courtyards to impress them. Looking at the differing levels of parenting skills across species around the world, we see why a tenth of bird species, including the fairy-wrens of Australia, have helpers at the nest who forgo their own reproduction to assist the breeding pair; how brood parasites and their hosts have engaged in evolutionary arms races; and how monogamous pairs share—or relinquish—their responsibilities. Illustrated throughout with beautiful photographs, Bird Love is a celebration of the global diversity of avian reproductive strategies.
