Описание:

In Vultures of the World, Keith L. Bildstein provides an engaging look at vultures and condors, seeking to help us understand these widely recognized but underappreciated birds.

Bildstein's latest work is an inspirational and long overdue blend of all things vulture. Based on decades of personal experience, dozens of case studies, and numerous up-to-date examples of cutting-edge science, this book introduces readers to the essential nature of vultures and condors. Not only do these most proficient of all vertebrate scavengers clean up natural and man-made organic waste but they also recycle ecologically essential elements back into both wild and human landscapes, allowing our ecosystems to function successfully across generations of organisms. With distributions ranging over more than three-quarters of all land on five continents, the world's twenty-three species of scavenging birds of prey offer an outstanding example of biological diversity writ large.

Included in the world's species fold are its most abundant large raptors—several of its longest lived birds and the most massive of all soaring birds. With a fossil record dating back more than fifty million years, vultures and condors possess numerous adaptions that characteristically serve them well but at times also make them particularly vulnerable to human actions. Vultures of the World is a truly global treatment of vultures, offering a roadmap of how best to protect these birds and their important ecology.

Описание:

This book reexamines current knowledge on the evolution, ecology, and conservation biology of both New World vultures (Cathartidae) and Old World vultures (Accipitridae) and seeks answers to past and present regional extinctions, colorizations, and conservation questions. Extinct species of both families are examined, as is the disputed evidence for familial similarities and differences currently under review by geneticists and ornithologists.

Conservation questions concern the extent to which recent land cover change (deforestation, urbanization, and desertification), wildlife depletions, and pollution have affected scavenging vultures. Such changes are examined as both positive and negative for vultures--a growing body of literature hints at the positive impacts of urban waste, more open forests, forest fires, landscape cultivation, road kills, and shore development, especially with increased attention to bird adaptation and new theories of adaptive management in conservation. These are contrasted with the conservation of other raptors and scavengers. Within new trends in conservation, with emphases on animal/human shared co-evolution in intensely habituated spaces, vulture conservation requires important new perspectives that contrast with the needs of other species conservation.
