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
DIVThe decline of bird species in a wide range of North American habitats—forests, prairies, shrublands, mountain regions, marshes, and deserts—has inspired two decades of intense scientific study of bird ecology and conservation. But for professional scientists and amateur birders alike, interpreting the results of these diverse studies is often complex and bewildering. This accessible book pulls together recent research on bird species and habitats to show how basic ecological principles apply in seemingly different situations. Robert A. Askins provides an engaging introduction to bird ecology and concepts of landscape ecology, focusing on such intriguing species as Bachman’s Warbler, Red Crossbill, Mountain Plover, and Marbled Murrelet. Understanding the ancient landscapes of North America and how humans have changed them, Askins says, is essential for devising plans to protect and restore bird populations. In addition to such obvious changes to the landscape as the clearing of forests and plowing of prairies, more subtle changes also dramatically affect birds. Species may disappear when we interrupt natural disturbances by suppressing wildfires or trapping out beaver, or when we disrupt habitat with roads and housing developments. Askins challenges some of the assumptions that underlie current conservation efforts and offers concrete recommendations, based on sound ecological principles, for protecting the rich natural diversity of North America’s birds./div

Book Description
Whether you watch birds on the shores of Long Island, at the Bashakill Marsh, at Niagara Falls, or just at your backyard feeder, this volume will help you appreciate what our Empire State has to offer. It will give you a historical perspective, and it will tell you what we can hope to look forward to in the future if we are vigilant stewards of our natural world.—Governor George E. PatakiThe "bible" of the state's birders since its publication in 1974, John Bull's Birds of New York State has now been completely revised and updated by the Federation of New York State Bird Clubs. This eagerly awaited survey of bird life in the state today provides new and thorough accounts of all 451 species on the official New York State checklist. The book features 7 new maps—4 in full color—and 30 striking sketches by bird artist Dale Dyer.Birders will find chapters covering topics from the prehistoric birds of the region to contemporary bird habitats and the ways in which current classification is being affected by DNA data and research. The species accounts themselves pay particular attention to date parameters and frequency of occurrence, details that are important to the active birder. Where applicable, full subspecies discussions are included.Meticulously prepared by the editor, Emanuel Levine, and the more than 70 members of the Federation who served as authors, this book will prove invaluable to birdwatchers statewide—whether backyard feeder watchers, casual birders, or dyed-in-the-wool enthusiasts.
