Download or read book Waterfowl in Winter written by Milton Webster Weller and published by U of Minnesota Press. This book was released on 1988 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waterfowl in Winter was first published in 1988. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. The emphasis in research on waterfowl has traditionally focused on breeding as opposed to migrant or wintering birds. Scientists have long been interested in courtship, nest sites, laying, and brood-rearing, and they have also been concerned about losses of eggs, young, nesting hens, and breeding habitats, especially as they have affected the goal of increasing populations. But lately there has been an upsurge of interest and research on the migratory and wintering phases, and this volume offers ample evidence of the knowledge gained. The authors—105 waterfowl biologists—have contributed 47 chapters that range geographically from Alaska to northern South America, and from the Pacific Northwest to Nova Scotia and Florida. Their subjects include: distributional changes due to human influence; population trends and concerns over less common species; pairing and other behavior that occurs in the wintering areas and is vital to the success of the species; feeding ecology and body condition during winter; new habitats created by such activities as aquaculture and park development; losses of habitat due to development and drainage for alternate uses; lead poisoning and pollutants that are detrimental to waterfowl; habitat management for maintenance of successful populations now and in the future. Also presented are reports of workshop discussions outlining current issues and future research needs. Preparation of this volume was assisted by an editorial board comprising Bruce J. J. Batt, Robert H. Chabreck, Leigh H. Fredrickson, and Dennis G. Raveling.
Download or read book Chico George the Birds and Me written by Dorothy Chapman Saunders and published by Texas A&M University Press. This book was released on 2008 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: "When a mysterious manila envelope reached the hands of Henry "Milt" Reeves, no one could have anticipated the story that waited inside. Enclosed he found a manuscript - a typewritten carbon copy on onion-skin paper - written half a century earlier and yellowed with age. Each fragile page unfolded the first-person description of a trip Dorothy Chapman Saunders had taken to Mexico in 1948 and 1949 with her husband and seasoned ornithologist, George, to conduct field surveys of waterfowl and white-winged doves for the U.S. government." "Chico, George, the Birds, and Me presents Saunders's near-daily personal account of this five-month-long ornithological expedition and provides a glimpse into the dynamic life of a frontier biologist making her mark in a man's world." "Saunders adeptly describes the birds they saw and the survey work they did. She also charts the other details of their journey as they traveled south from Reynosa to Mexico City, then to Acapulco and Oaxaca, east to Veracruz, north to Tamaulipas and, finally, back to McAllen, Texas, Slowly chugging along in the under-powered jeep they affectionately dubbed "Chico," they explored lakes, lagoons, and volcanoes, Aztec ruins, markets, churches, and even old burro trails."--BOOK JACKET.

Download or read book Ducks Geese and Swans of North America written by Guy Baldassarre and published by JHU Press. This book was released on 2014-11-15 with total page 1183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The best-selling and authoritative reference book on waterfowl has been fully revised and updated by one of the world’s most respected waterfowl biologists. Honorable Mention for the PROSE Award for Excellence, Multivolume/Science of the Association of American Publishers Ducks, Geese, and Swans of North America has been hailed as a classic since the first edition was published in 1942. A must-have for professional biologists, birders, waterfowl hunters, decoy collectors, and wildlife managers, this fully revised and updated edition provides definitive information on the continent's forty-six species. Maps of both winter and breeding ranges are presented with stunning images by top waterfowl photographers and the acclaimed original artwork of Robert W. (Bob) Hines. Originally authored by F. H. Kortright and later revised by Frank Bellrose, this latest edition, which has been meticulously updated by renowned waterfowl biologist Guy Baldassarre, continues the legacy of esteemed authors. Each species account contains in-depth sections on: • identification • distribution • migration behavior • habitat • population status • breeding biology • rearing of young • recruitment and survival • food habits and feeding ecology • molts and plumages • conservation and management To facilitate identification, the species accounts also include detailed illustrations of wings. An appendix contains comparative illustrations of ducklings, goslings, and cygnets. This edition of Ducks, Geese, and Swans consists of two volumes, printed in full color, and packaged in a slipcase, along with a CD containing references and additional maps.

Book excerpt: A review and synthesis of existing information were used to develop a model for evaluating wintering habitat quality for the northern pintail along the Gulf of Mexico. The model is scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1 (optimum habitat). Habitat suitability indices are designed for use with the Habitat Evaluation Procedures previously developed by the U.S. Fish and Wildlife Service.

Download or read book Whooping Cranes Biology and Conservation written by and published by Academic Press. This book was released on 2018-09-04 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whooping Cranes: Biology and Conservation covers one of the most endangered birds in North America, and the subject of intense research and highly visible conservation activity. The volume summarizes current biological information on Whooping Cranes and provides the basis for future research necessary for conservation of this species. This edited volume concentrates on work completed in the past 20 years in the areas of population biology, behavior and social structure, habitat use, disease and health, captive breeding, and Whooping Crane conservation. Much of the information presented comes from the study and management of remnant and reintroduced populations of Whooping Cranes in the field; some information is from experimentation and breeding of captive Whooping Cranes. Whooping Cranes: Biology and Conservation seeks to inform and galvanize action dedicated to meeting the challenges faced by Whooping Crane managers and conservationists. Thus, it describes one model of endangered species conservation and restoration that will interest a wide audience: professionals that work on cranes; researchers in the fields of small population biology, endangered species, and avian ecology; wildlife veterinarians and those involved in avian husbandry; administrators of management agencies or conservation organizations; conservationists in other fields; teachers of conservation biology or ornithology and their students; and the educated general public. Presents a comprehensive treatment of the biology and ecology of Whooping Cranes, including biology of both remnant and reintroduced populations of Whooping Cranes Describes efforts over the past 45 years on conservation and the challenges of reintroducing an endangered species Includes chapters from a variety of disciplinary and scale perspectives, ranging from evolution, to population ecology, behavior, habitat use, large landscape conservation, conflict, and conservation efforts Features contributions that are readable, yet technically complete and fully referenced Provides an example of partnership and collegial action that integrates information produced by scientific research and operational wildlife management Edited and written by the leading Whooping Crane scholars and practitioners focused on this high-profile species of conservation concern
