“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

For more than a decade ornithologists have suspected that migrant landbird populations in the United States and Canada are declining. Fragmented forests in the northern breeding grounds and the loss of habitats in tropical wintering zones have been suggested as two major factors in the population declines. This is the first technical volume to focus exclusively on the question of northern hemispheric migratory landbird declines and their conservation. More than one hundred leading scholars working in the Americas and the Caribbean report on the problems facing these birds and suggest strategies for research and conservation. The book details the basic ecology of many Neotropical migrant landbirds in both temperate and tropical regions. Individual reports--each with a Spanish abstract--probe the reasons for population changes, discuss species behavior during summer and winter months, and gauge the impact of environmental events on landbirds. This book arose out of a 1989 symposium at Woods Hole, Massachusetts, hosted by the Manomet Bird Observatory--a meeting widely credited for bringing Neotropical migrant landbird conservation to the forefront of attention.

P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological biological observation station in the world (see first chapter "In Memory of Vogelwarte Rossitten"). This area later received enormous impetus when ex perimental research on the subject was begun: the large-scale bird-ringing experiment initiated in Rossitten in 1903 by Johannes Thienemann (who was inspired by the pioneering studies of C. C. M. Mortensen), the experiments on photoperiodicity carried out by William Rowan in the 1920s in Canada and retention and release experiments performed by Thienemann in the 1930s in Rossitten, the first experimental study on the orientation of migratory birds. After the Second World War, migration research, while continuing in the previous areas, also expanded into new directions such as radar ornithology, ecophysiology and hormonal control mechanisms, studies of evolution, ge netics, telemetry and others.

Home to large numbers of people, sources of water, centres of tourism, and sensitive ecological zones, mountain environments share distinctive climactic characteristics. Once regarded as economically non-viable regions, mountains now attract major investment as sites of tourism, hydro-power and communication routes. This book brings together some of the current work on the physical and human ecology of mountain environments, the impacts of climate change, the processes involved and their observation and prediction.

The Migration Ecology of Birds, Second Edition covers all aspects of this absorbing subject, including migratory processes, problems of navigation and vagrancy, timing and physiological control of migration, large-scale movement patterns, the effects of recent climate change, the problems that migrants face, and the factors that limit their populations. This book provides a thorough and in-depth review of the state of the science, with the text supplemented by abundant tables, maps and diagrams. Written by a world-renowned avian ecology and migration researcher, this book reveals the extraordinary adaptability of birds to the variable and changing conditions across the globe. This book represents the most updated and detailed review of bird migration, its evolution, ecology and bird physiology. Written in a clear and readable style, it will appeal not only to migration researchers in the field and ornithologists, but to anyone with an interest in this fascinating subject. - Features updated and trending ecological aspects, including various types of bird movements, dispersal and nomadism, and how they relate to food supplies and other external conditions - Contains numerous tables, maps, diagrams, a glossary, and a bibliography of more than 3,000 up-to-date references - Written by an active researcher with a distinguished career in avian ecology, including migration research
