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.

Available in PDF, EPUB and Kindle. Book excerpt: More than 30 species of North American waterfowl winter in the Neotropics, with distributions that extend south of the United States into Mexico, Central America, South America, or the Caribbean islands. Leopold (1959) suggested that 9-17% of the total North American waterfowl population crosses the U.S.-Mexico border during migration. Saunders and Saunders (1981) reported sizable numbers of northern shoveler (Anas clypeata), gadwall (A. strepera), northern pintail (A.acuta), green-winged (A. crecca), and redheads (Aythya americana)wintering in Mexico. Bellrose (1980) suggested that the majority of black brant (Branta bernicla), blue-winged teal (Anas discors), and cinnamon teal (A. cyanoptera) winter south of the United States.
