Book Description
This Technical Memorandum provides extensive data on birdlife at Wallops Island, a mid-Atlantic barrier island, and home to NASA Wallops Flight Facility's launch range. Variation in the distribution and abundance of many species is considerable in this region, which is centered along the north-south axis of the Delmarva Peninsula. Data (date of occurrence and general abundance) and analysis of the Island's diverse habitat structure are provided. A total of 244 species of birds are recorded; a summary of the records are given in the Species Accounts and the Appendix. Vaughn, Charles R. Wallops Flight Facility...
The History of Ornithology in Virginia

Book Description
Host to a large and diverse bird population as well as a long human history, Virginia is arguably the birthplace of ornithology in North America. David W. Johnston's History of Ornithology in Virginia, the result of over a decade of research, is the first book to address this fascinating element of the state's natural history. Tertiary-era fossils show that birds inhabited Virginia as early as 65 million years ago. Their first human observers were the region's many Indian tribes and, later, colonists on Roanoke Island and in Jamestown. Explorers pushing westward contributed further to the development of a conception of birds that was distinctively American. By the 1900s planter-farmers, naturalists, and government employees had amassed bird records from the Barrier Islands and the Dismal Swamp to the Blue Ridge and Appalachian Mountains. The modern era saw the emergence of ornithological organizations and game laws, as well as increasingly advanced studies of bird distribution, migration pathways, and breeding biology. Johnston shows us how ornithology in Virginia evolved from observations of wondrous creatures to a sophisticated science recognizing some 435 avian species. David W. Johnston taught ornithology at the University of Virginia's Mountain Lake Biological Station for nearly two decades and has edited numerous ecological studies as well as the Journal of Field Ornithology and Ornithological Monographs.

Migration : The Biology of Life on the Move
Author: Davis Hugh Dingle Professor in the Department of Entomology and Center for Population Biology University of CaliforniaPublisher: Oxford University Press, USA

Book Description
Migration is one of the most fascinating and dramatic of all animal behaviors. Historically, however, the study of migration has been fragmented, with ornithologists, entomologists, and marine biologists paying little attention to work outside their own fields. This treatment of the subject shows how comparisons across taxa can in fact illuminate migratory life cycles and the relation of migration to other movements. The book thus takes an integrated ecological perspective, focusing on migration as a biological phenomenon. The work is divided into four parts, each with a brief introductory section. Part I defines migration, gives examples, and places migration in the spectrum of movement behaviors, concluding with a chapter on methods for its study. Part II focuses on proximate mechanisms, including physiology and morphology (and the constraints associated with them), the interactions between migration and wind and current patterns, and the various orientation and navigation mechanisms by which migrants find their way about. Part III on the evolution of migratory life histories addresses the evolutionary and ecological basis for migration and the roles of migration not only in the lives of organisms, but also in the ecological communities in which they live. Part IV is devoted to a brief consideration of migration and its relation to pest management and conservation. As a major contribution to a vital subject, this work will be valued by all researchers and students in the field of animal behavior, ecology, and zoology.
