Download or read book The North American Perching and Dabbling Ducks written by Paul Johnsgard and published by Lulu.com. This book was released on 2017-03 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, the fourth in a series of books that collectively update and expand P.A. Johnsgard's 1975 The Waterfowl of North America, summarizes research findings on this economically and ecologically important group of waterfowl. The volume includes the mostly tropical perching duck tribe Cairinini, of which two species, the muscovy duck and the wood duck, are representatives. Both species are adapted for foraging on the water surface, mostly on plant materials, but typically perch in trees and nest in elevated tree cavities or other elevated recesses. This volume also includes the dabbling, or surface-feeding, duck tribe Anatini, a large assemblage of duck species that mainly forage on the water surface but nest on the ground, or only very rarely in elevated locations. Of this tribe, 12 species that regularly breed in North America are included, among them such familiar species as mallards, wigeons, pintails, and teal. Descriptive accounts of the distributions, populations, ecologies, social-sexual behaviors, and breeding biology of all these species are provided, together with distribution maps. Five additional Eurasian and West Indian species have been reported several times in North America; these have been included with more abbreviated accounts, but all 17 species are illustrated by drawings, photographs, or both. The text includes about 84,000 words and contains more than 1,000 references. There are also 12 distribution maps, 21 drawings, 28 photographic plates, and 58 anatomical or behavioral sketches.

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.

This book was released on 1982 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sample of 365 stands of seeded nesting cover (mixtures of cool-season grasses and legumes) was studied in the glaciated prairie pothole region during 1977-79. Measurements of species composition, canopy cover, plant height, and visual obstruction values differed with stand age but only in a general way when results from over the entire region were pooled. Maximum values for plant height and visual obstruction occurred once per stand during the first 10 growing seasons. Although the year of maximum growth was variable and unpredictable, stands showed trends of degeneration in height and visual obstruction after the year of maximum growth.
