Why do birds migrate -- and just how do they do it? The Migration of Birds is a comprehensive illustrated presentation of the mysteries of bird migration. Ornithologist Janice M. Hughes describes the findings of the most recent research and surveys as-yet-unanswered questions. She unravels the exciting contributions of cutting-edge technological innovations and scientific developments. Over 70 stunning full-color photographs show some of the world's most dauntless voyagers. Maps show migration routes, and illustrations depict the mechanics of flying. The text is engaging and straightforward as well as authoritative and comprehensive, covering: Bird migration through human history, with profiles of Chinese cranes and phalaropes The five Ws of avian migration, with profiles of shrikes and Arctic terns The phenomenon of flight, with profiles of wheatears and dippers How birds find their way, with profiles of redwings, fieldfares and Bohemian waxwings Migratory birds in peril. This book will fascinate birders, naturalists and conservationists as well as general readers.

Until recently, little was known about the lives of songbirds during their travels from autumn until spring. Now scientists have documented mass migrations over the Gulf of Mexico, identified the voices of migrants in the night sky, and showed how songbirds navigate using stars, polarized light, and magnetic fields. Miyoko Chu explores the intricacies underlying the ebb and flow of migration, the cycle of seasons, and the interconnectedness between distant places. Songbird Journeys pays homage to the wonder and beauty of songbirds while revealing the remarkable lives of migratory birds and the scientific quest to answer age-old questions about where songbirds go, how they get there, and what they do in the far-flung places they inhabit throughout the year.

The story of an ornithologist's journey to trace the spring migration of songbirds from the southern border of the United States through the heartland and into Canada. In late March 2015, ornithologist Bruce M. Beehler set off on a solo four-month trek to track songbird migration and the northward progress of spring through America. Traveling via car, canoe, and bike and on foot, Beehler followed woodland warblers and other Neotropical songbird species from the southern border of Texas, where the birds first arrive after their winter sojourns in South America and the Caribbean, northward through the Mississippi drainage to its headwaters in Minnesota and onward to their nesting grounds in the north woods of Ontario. In North on the Wing, Beehler describes both the epic migration of songbirds across the country and the gradual dawning of springtime through the U.S. heartland--the blossoming of wildflowers, the chorusing of frogs, the leafing out of forest canopies--and also tells the stories of the people and institutions dedicated to studying and conserving the critical habitats and processes of spring songbird migration. Inspired in part by Edwin Way Teale's landmark 1951 book North with the Spring, this book--part travelogue, part field journal, and part environmental and cultural history--is a fascinating first-hand account of a once-in-a-lifetime journey. It engages readers in the wonders of spring migration and serves as a call for the need to conserve, restore, and expand bird habitats to preserve them for future generations of both birds and humans.

This book presents an up-to-date, detailed and thorough review of the most fascinating ecological findings of bird migration. It deals with all aspects of this absorbing subject, including the problems of navigation and vagrancy, the timing and physiological control of migration, the factors that limit their populations, and more. Author, Ian Newton, reveals the extraordinary adaptability of birds to the variable and changing conditions across the globe, including current climate change. This adventurous book places emphasis on ecological aspects, which have received only scant attention in previous publications. Overall, the book provides the most thorough and in-depth appraisal of current information available, with abundant tables, maps and diagrams, and many new insights. Written in a clear and readable style, this book appeals not only to migration researchers in the field and Ornithologists, but to anyone with an interest in this fascinating subject. * Hot ecological aspects include: various types of bird movements, including dispersal and nomadism, and how they relate to food supplies and other external conditions * Contains numerous tables, maps and diagrams, a glossary, and a bibliography of more than 2,700 references * Written by an active researcher with a distinguished career in avian ecology, including migration research

The Avian Migrant

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.
