The destruction of the tropical forest is one of the major problems of our time. Vast areas are rapidly becoming wastelands which support only a few tough weeds, perhaps some cattle, and the farms allowed to the poor. This book provides a vision of hope: in Latin America. Africa. And South East Asia, growing numbers of people are developing techniques specifically designed to promote the wise use and preservation of remaining forest lands. However, these grassroots strategies are often ignored in favour of grandiose schemes which inevitably fail. This pattern must be broken now or the tropical forests will be lost forever.

For centuries biologists have tried to understand the underpinnings of avian migration: where birds go and why, why some migrate and some do not, how they adapt to a changing environment, and how migratory systems evolve. Twenty-five years ago the answers to many of these questions were addressed by a collection of migration experts in Keast and Morton's classic work Migrant Birds in the Neotropics. In 1992, Hagan and Johnston published a follow-up book, Ecology and Conservation of Neotropical Migrant Landbirds. In Birds of Two Worlds Russell Greenberg and Peter Marra bring together the world's experts on avian migration to discuss its ecology and evolution. The contributors move the discussion of migration to a global stage, looking at all avian migration systems and delving deeper into the evolutionary foundations of migratory behavior. Readers interested in the biology, behavior, ecology, and evolution of birds have waited a decade to see a worthy successor to the earlier classics. Birds of Two Worlds will complete the trilogy and become indispensable for ornithologists, evolutionary biologists, serious birders, and public and academic libraries.
