Download or read book The Narrow Edge written by Deborah Cramer and published by Yale University Press. This book was released on 2015-04-28 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thousands of ravenous tiny shorebirds race along the water’s edge of Delaware Bay, feasting on pin-sized horseshoe-crab eggs. Fueled by millions of eggs, the migrating red knots fly on. When they arrive at last in their arctic breeding grounds, they will have completed a near-miraculous 9,000-mile journey that began in Tierra del Fuego. Deborah Cramer followed these knots, whose numbers have declined by 75 percent, on their extraordinary odyssey from one end of the earth to the other—from an isolated beach at the tip of South America all the way to the icy tundra. In her firsthand account, she explores how diminishing a single stopover can compromise the birds' entire journey, and how the loss of horseshoe crabs—ancient animals that come ashore but once a year—threatens not only the survival of red knots but also human well-being: the unparalleled ability of horseshoe-crab blood to detect harmful bacteria in vaccines, medical devices, and intravenous drugs safeguards human health. Cramer offers unique insight into how, on an increasingly fragile and congested shore, the lives of red knots, horseshoe crabs, and humans are intertwined. She eloquently portrays the tenacity of small birds and the courage of many people who, bird by bird and beach by beach, keep red knots flying.

Download or read book Neotropical Migratory Birds written by Richard DeGraaf and published by Cornell University Press. This book was released on 2019-06-07 with total page 699 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Endangered and Disappearing Birds of Appalachia and the Southeast written by Matt Williams and published by University Press of Kentucky. This book was released on 2024-03-05 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the most unforgiving of concrete jungles to the pastoral reaches of the countryside, birds are among the most plentiful and plainly visible animals on the planet. For millions of years, they have survived in every known biome, carving out ecological niches for themselves and their offspring and often thriving. But this remarkable adaptability can only go so far. With the recent acceleration of habitat loss, climate change, spread of invasive species, and other detrimental environmental developments, birds are disappearing across the world. Yet despite such wide-ranging decimation, birdwatching remains one of the fastest growing hobbies in the United States. Endangered and Disappearing Birds of Appalachia and the Southeast, by award-winning author and photographer Matt Williams, is an essential guide for the bird-curious in the Appalachian and southeastern regions of the United States. Combining brilliant photography with taxonomic classification, identification tips, and other information, the book goes beyond the scope of a traditional field guide. Each profile includes descriptions of current species-conservation efforts, as well as tips on how to get involved in the ongoing work to save these endangered creatures. This carefully compiled guide offers a detailed introduction to the birds that most need our help and to the steps we can all take to protect their future.

Available in PDF, EPUB and Kindle. Book excerpt: "Wetland use and selection by species of waterbirds (shorebirds, wading birds, gulls, terns, grebes, cormorants, and pelicans) between the Rio Grande and Galveston Bay in coastal Texas were studied during September and November of 1991-92 and during January and March of 1992-93. Based on a stratified (by dominant land use) random sample of 64.75-ha plots, 88 species of waterbirds using wetlands were observed. Ranks of density and proportion of feeding bird indicated that cormorants and pelicans preferred wetlands with less than 30% vegetation. Gulls, terns, and skimmers preferred certain types of estuarine and lacustrine wetlands with less than 30% vegetation, especially estuarine subtidal rock bottom rubble types. Grebes and rails selectively used palustrine aquatic-bed rooted vascular and unconsolidated bottom mud wetland types. Herons, egrets, and bitterns preferred certain types of lacustrine and estuarine wetlands. Shorebirds used estuarine intertidal wetlands. Waterbird management should focus on 26 of the 82 wetland types that we prioritized in the coastal plains of Texas. Management should focus on protecting, enhancing, or restoring complexes of various wetland types, especially estuarine aquatic-bed and intertidal unconsolidated substrate types"--Page 1
