Book Description
The eight currently recognized species of North American geese are part of a familiar group of birds collectively called waterfowl, all of which are smaller than swans and generally larger than ducks. They include the most popular of our aquatic gamebirds, with several million shot each year by sport hunters. Our two most abundant waterfowl, the Canada goose and snow goose, have populations collectively totaling about 15 million individuals. Like swans, the lifelong pairbonding of geese, their familial care, and prolonged social attachment to their offspring are legendary. Their seasonal migratory flights sometimes span thousands of miles, and the sight of their long, wavering flight formations are as much the symbols of seasonal change as are the spring songs of cardinals or the appearance of autumnal leaf colors. This book describes each species' geographic range and subspecies, its identification traits, weights and measurements, and criteria for its age and sex determination. Ecological and behavioral information includes each species' breeding and wintering habitats, its foods and foraging behavior, its local and long distance movements, and its relationships with other species. Reproductive information includes each species' age of maturity, pair-bond pattern, pair-forming behaviors, usual clutch sizes and incubation periods, brooding behavior, and postbreeding behavior. Mortality sources and rates of egg, young, and adult losses are also summarized, and each species' past and current North American populations are estimated. In addition to a text of nearly 60,000 words, the book includes 8 maps, 21 line drawings, and 28 photographs by the author, as well as more than 700 literature citations.

Book Description
This open access book reviews the importance of ecological functioning within rangelands considering the complex inter-relationships of production agriculture, ecosystem services, biodiversity, and wildlife habitat. More than half of all lands worldwide, and up to 70% of the western USA, are classified as rangelands—uncultivated lands that often support grazing by domestic livestock. The rangelands of North America provide a vast array of goods and services, including significant economic benefit to local communities, while providing critical habitat for hundreds of species of fish and wildlife. This book provides compendium of recent data and synthesis from more than 100 experts in wildlife and rangeland ecology in Western North America. It provides a current and in-depth synthesis of knowledge related to wildlife ecology in rangeland ecosystems, and the tools used to manage them, to serve current and future wildlife biologists and rangeland managers in the working landscapes of the West. The book also identifies information gaps and serves as a jumping-off point for future research of wildlife in rangeland ecosystems. While the content focuses on wildlife ecology and management in rangelands of Western North America, the material has important implications for rangeland ecosystems worldwide.

Book Description
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.

Book Description
In this beautifully illustrated guide, two practicing wildlife biologists describe the life histories of forty-five species of ducks, geese, and swans that occur in Texas. For common species and those that breed in the state, each account begins with an interesting fact (such as, “Red-breasted Mergansers have been clocked at over 80 mph, the fastest recorded flight speed for a duck . . .”) and provides information on Texas distribution and harvest, population status, diet, range and habitats, reproduction, and appearance. Exquisite photographs, informative distribution maps, and a helpful source list accompany the species descriptions, and the book offers a glossary and full bibliography for those who want to explore the literature further. With the degradation and disappearance of the inland and coastal habitats that these birds depend upon, the natural history of these waterfowl species provides a vital reminder of the interconnectedness and crucial importance of all wetlands. Birders, biologists, landowners, hunters, outdoor enthusiasts, and all those interested in the health and preservation of our coastal and inland wetland resources will enjoy and learn from this book.
