Book Description
Ten years have passed since the first edition of this book. During that time the field of bird migration has experienced many advances which are reflected in this second edition. No other book exists to bring together the vast amount of information currently available on the subject of bird migration. Includes discussion of evolution and history of bird migration, physiology, orientation mechanisms and threats to migrations and is accessible to experts as well as amateurs.

Book Description
Thrushes, warblers, vireos, and tanagers are probably the most familiar of the Neotropical migrants--birds that breed in the United States and Canada, then journey to spend the winter in the Caribbean, Mexico, or southward. But this extraordinary group actually comprises a large number of diverse species, including waterfowl, shorebirds, terns, hawks, flycatchers, and hummingbirds. In their compendious review of information on these birds, Richard M. DeGraaf and John H. Rappole illuminate the need for a thorough understanding of the ecology of each species, one that exte4nds throughout the entire life cycle. The authors argue convincingly that conservation efforts must be based on such an understanding and carried out across a species' range--not limited to the breeding grounds. This book is the first to summarize in one volume much-needed practical data about the distribution and breeding habitat requirements of migratory birds in North and South America. The body of the book consists of natural history accounts of more than 350 species of Neotropical migrants, including a brief description of each bird's range, status, habitats on breeding grounds, nest site, and wintering areas. The authors provide a complete range map of each species' distribution in the Western Hemisphere as well as notes on the distribution--basic data that until recently have largely been unavailable in usable form to ornithologists and land and resource managers. An appendix lists species that are increasing or decreasing at significant rates in various physiographic regions of North America.

Book Description
This report was prepared in support of the National Fish and Wildlife Foundation's Neotropical Migratory Bird Conservation Program and the USDA Forest Service's role in the program. Recent analyses of data on forest-dwelling species, many of which are neotropical migrants, show population declines in many North American areas. The literature review summarizes current information on population trends of neotropical migratory birds and the factors affecting migrant populations on the breeding and wintering grounds. Opportunities for research, monitoring, and conservation of these migrants on Forest Service lands are discussed.

Book Description
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.

Book Description
Changes in seasonal movements and population dynamics of migratory birds in response to ongoing changes resulting from global climate changes are a topic of great interest to conservation scientists and birdwatchers around the world. Because of their dependence on specific habitats and resources in different geographic regions at different phases of their annual cycle, migratory species are especially vulnerable to the impacts of climate change. In Bird Migration and Global Change, eminent ecologist George W. Cox brings his extensive experience as a scientist and bird enthusiast to bear in evaluating the capacity of migratory birds to adapt to the challenges of a changing climate. Cox reviews, synthesizes, and interprets recent and emerging science on the subject, beginning with a discussion of climate change and its effect on habitat, and followed by eleven chapters that examine responses of bird types across all regions of the globe. The final four chapters address the evolutionary capacity of birds, and consider how best to shape conservation strategies to protect migratory species in coming decades. The rate of climate change is faster now than at any other moment in recent geological history. How best to manage migratory birds to deal with this challenge is a major conservation issue, and Bird Migration and Global Change is a unique and timely contribution to the literature.

Book Description
“Rigorous and well defended . . . Faaborg makes many fresh and, in some cases, provocative points regarding management guidelines for migrant birds.” —Kenneth Able, Great Plains Research In the 1980s, numerous scientific surveys documented both declining bird populations, especially among Neotropical songbirds that winter in the tropics, and the loss of tropical rain forest habitat. Drawing the seemingly obvious conclusion, scientists and environmental activists linked songbird declines to loss of tropical habitats and alerted the world to an impending ecological catastrophe. Their warnings led to the establishment of the Neotropical Migratory Bird Conservation Program, also known as Partners in Flight, the self-proclaimed largest conservation effort in history. Looking back over more than a decade of efforts to save migrant birds, John Faaborg offers the first serious evaluation of the state of songbird populations today, the effectiveness of conservation programs such as Partners in Flight, and the reliability and completeness of scientific research on migrant birds. Taking neither an alarmist nor a complacent approach, he shows that many factors besides habitat loss affect bird populations and that Neotropical migrants as a group are not declining dramatically, though some species adapt to habitat alteration more successfully than others. Faaborg’s state-of-the-art survey thus clarifies the kinds of information we will need and the conservation efforts we should undertake to ensure the long-term survival of Neotropical migrant birds. “Presents a carefully and closely reasoned argument about the magnitude of the conservation problems facing migrant birds, how we can reduce these problems, and how current conservation efforts have enormous value even if there is no immediate crisis.” —Scott K. Robinson, Professor and Head, Department of Animal Biology, University of Illinois
