Download or read book Nesting Ecology of Canada Geese in the Hudson Bay Lowlands of Ontario written by Dennis G. Raveling and published by [Toronto, Ont.] : Ontario Ministry of Natural Resources. This book was released on 1977 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Report is in two major sections: nesting ecology and population limitations. Objectives were to examine apparent optimum and accomplished reproductive rates, habitat preferences, and density and sparing of nests in relation to the regulation of population size. The nesting ecology was also examined to provide insight into the factors limiting goose numbers.
Download or read book Nesting Ecology of Eastern Prairie Population Canada Geese written by Scott Edward Walter and published by Ann Arbor, Mich. : University Microfilms International. This book was released on 1999 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Ducks Geese and Swans of North America written by Guy A. Baldassarre and published by JHU Press. This book was released on 2014 with total page 1183 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 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. Guy Baldassarre has hit the target. His remake of the Kortright/Bellrose classic provides good biological descriptions, wonderful photographs and illustrations, and easy-to-understand information about waterfowl. I would encourage every hunter and enthusiast to have these books as an educational guide to waterfowl and their needs.--H. Dale Hall, CEO, Ducks Unlimited, Inc. When, as an eleven-year-old in 1942, I read F. H. Kortright's first edition of this book, it altered the trajectory of my life. Every subsequent edition, including this latest update by Guy Baldassarre, has improved the landmark reference. I can't imagine that anyone interested in waterfowl or wetlands can live without this indispensable book.--Paul A. Johnsgard, University of Nebraska-Lincoln Creating a brand-new version of such a timeless and previously revised classic is a risky venture indeed, but nobody could be better suited for this monumental task than Guy Baldassarre. He has created a stunning new classic, at once magnificent in its visual appeal and truly comprehensive in its scientific breadth and depth. Hats off to Guy for dedicating himself to this project with such obvious passion, patience, and skill. This book absolutely belongs on the shelf or coffee table of anyone who has ever marveled at waterfowl, whether through their binoculars or from inside the duck blind.--John W. Fitzpatrick, Cornell Laboratory of Ornithology Guy Baldassarre was a professor of wildlife ecology at the State University of New York College of Environmental Science and Forestry in Syracuse until his death in 2012. He is the coauthor of the textbook, Waterfowl Ecology and Management.

Download or read book Partnerships in Birds The Study of Monogamy written by Jeffrey M. Black and published by Oxford University Press, UK. This book was released on 1996-05-30 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some birds mate for life, while others have many partners. Why? In this book, fourteen classic studies of bird behaviour are brought together to compare the different partnership patterns from ecological and evolutionary perspectives. Often there is a battle of the sexes, as individual birds behave in the way that serves their best interests. Introductory and concluding chapters review the latest thinking on this fascinating subject. - ;Some birds mate for life, while others have many partners. In this book, fourteen studies are brought together to compare different partnership patterns from ecological and evolutionary perspectives. The subjects have been chosen to include the same species living in different habitats (Sparrowhawks) and at different population densities (Great Tits). There are comparisons between closely related species (Mute Swans and Bewick's Swans). The studies span the globe and the behavioural gradient, from Iceland's strictly monogamous Whooper Swans to Australia's sexually promiscuous Splendid Fairy-wrens. In all cases, sexual and social relationships strongly influence a bird's survival and breeding success. -
