The purpose of migration, regardless of the distance involved, is to exploit two or more environments suitable for survival or reproduction over time, usually on a seasonal basis. Yet individual organisms can practice the phenomenon differently, and birds deploy unique patterns of movement over particular segments of time. Incorporating the latest research on bird migration, this concise, critical assessment offers contemporary readers a firm grasp of what defines an avian migrant, how the organism came to be, what is known about its behavior, and how we can resolve its enduring mysteries. John H. Rappole's sophisticated survey of field data clarifies key ecological, biological, physiological, navigational, and evolutionary concerns. He begins with the very first migrants, who traded a home environment of greater stability for one of greater seasonality, and uses the structure of the annual cycle to examine the difference between migratory birds and their resident counterparts. He ultimately connects these differences to evolutionary milestones that have shaped a migrant lifestyle through natural selection. Rather than catalogue and describe various aspects of bird migration, Rappole considers how the avian migrant fits within a larger ecological frame, enabling a richer understanding of the phenomenon and its critical role in sustaining a hospitable and productive environment. Rappole concludes with a focus on population biology and conservation across time periods, considering the link between bird migration and the spread of disease among birds and humans, and the effects of global warming on migrant breeding ranges, reaction norms, and macroecology.

In 2015, ornithologist Bruce M. Beehler set off on a solo backroads journey to trace the spring migration of songbirds from the southern border of the United States through the U.S. heartland and north into Canada. Traveling via car, canoe, bike, and on foot, Beehler followed migrant wood warblers and other songbirds from the Texas coast, up the Mississippi drainage to its headwaters in Minnesota and onward to the birds' nesting grounds in the north woods of Ontario. Engaging readers in the wonders of the spring migration, this book is a call to conserve, restore, and expand bird habitats to preserve them for the well-being of future generations of both birds and humans.

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.

The Ruff is a fascinating species whose elaborate breeding behaviour has captivated ornithologists for decades. Their communal display grounds, or leks, provide an extreme example of a social system widespread in birds and other animals, in which brilliantly plumaged males seemingly compete for the attention of passing females. In this book, Johan van Rhijn explores this complex and intricate drama, both to lay bare the details of the players' private lives, and to provide a means of exploring the wider variety of wader breeding systems. Strands of evidence for all aspects of the Ruffs life, in and out of the breeding season, come together to give a thought-provoking insight into this important area of biology. Specialists and birdwatchers alike will have much to learn from this intriguing story and the insights it provides.

The Rise of Birds

A small set of fossilized bones discovered almost thirty years ago led paleontologist Sankar Chatterjee on a lifelong quest to understand their place in our understanding of the history of life. They were clearly the bones of something unusual, a bird-like creature that lived long, long ago in the age of dinosaurs. He called it Protoavis, and the animal that owned these bones quickly became a contender for the title of "oldest known bird." In 1997, Chatterjee published his findings in the first edition of The Rise of Birds. Since then Chatterjee and his colleagues have searched the world for more transitional bird fossils. And they have found them. This second edition of The Rise of Birds brings together a treasure trove of fossils that tell us far more about the evolution of birds than we once dreamed possible. With no blind allegiance to what he once thought he knew, Chatterjee devours the new evidence and lays out the most compelling version of the birth and evolution of the avian form ever attempted. He takes us from Texas to Spain, China, Mongolia, Madagascar, Australia, Antarctica, and Argentina. He shows how, in the "Cretaceous Pompeii" of China, he was able to reconstruct the origin and evolution of flight of early birds from the feathered dinosaurs that lay among thousands of other amazing fossils. Chatterjee takes us to where long-hidden bird fossils dwell. His compelling, occasionally controversial, revelations—accompanied by spectacular illustrations—are a must-read for anyone with a serious interest in the evolution of "the feathered dinosaurs," from vertebrate paleontologists and ornithologists to naturalists and birders. -- Alan Feduccia, University of North Carolina
