Book Description
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.

Book Description
"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.

Book Description
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.
