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.

Successful management of Canada geese (Branta canadensis) requires an understanding of the factors which govern annual variation in reproductive success. We examined variation in nesting phenology, clutch size, nest survival, partial predation, egg size, and nest density for Eastern Prairie Population (EPP) Canada geese using data collected from 3 study areas in northern Manitoba from 1976-1996. The timing of nest initiation varied among years, and this variation was largely related to local weather conditions during the month of May. Mean clutch size declined with later annual nesting phenology, suggesting that delayed nesting results in higher energetic demands and reduced endogenous reserves for EPP geese. The relation between clutch size and relative nest initiation date within years was not linear, with the largest clutches being produced near the midpoint of initiation, and this relation was likely driven by a reduced allotment of nutrient reserves to egg production by early-nes.
