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 The Teal written by Matthieu Guillemain and published by Bloomsbury Publishing. This book was released on 2014-10-23 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small, noisy and colourful, the Teal is a familiar duck throughout the wetlands and waterways Europe and Asia. Once hunted extensively for the pot, its numbers have recovered and it is now one of our commonest species of waterfowl. A flagship species for wetland conservation, the Teal is also an excellent model species for ecological research, and this forms the spine of this new Poyser monograph. The Teal looks at distribution and trends in numbers, foraging ecology, breeding behaviour), population dynamics, management and conservation of teal, looking at both the Eurasian Common Teal and its North American equivalent, the Green-winged Teal (which until relatively recently was considered to be the same species). The book provides a scientifically robust account on which wetland managers, research scientists and the ornithological community may rely, with wider implicatons for the conservation and management of other waterfowl, and for ecological research in general.
Download or read book The Ecology of Adaptive Radiation of Dabbling Ducks Anas Spp written by David Brent Gurd and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2005 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ecological theory of adaptive radiation proposes that three processes are responsible for the evolution of a single ancestor into a clade of species: divergence in phenotype between contrasting environments; divergence in phenotype caused by negative interspecific interactions; and ecological speciation. I tested for evidence of these processes among sympatric dabbling ducks (Anas spp.), a putative adaptive radiation. Divergent selection between environments requires a trade-off in the ability of phenotypes to exploit resources in different environments. I tested whether variation in bill morphology imposes a performance trade-off when ducks filter-feed in environments containing different size-frequency distributions of prey and indigestible detritus. Experiments demonstrated that ducks could avoid ingesting detritus when prey and detritus differ in size. Foraging models based on filter-feeding biomechanics predict prey size selection causes a decline in filtration rates and that the form of this trade-off depends on interspecific differences in bill morphology. To test these models, I used them to predict the results of manipulative foraging experiments on 2 species reported in the literature. There was overall agreement between model predictions and reported differences in filtration rates, particle retention probabilities and ingestion rates, both between species and due to variation in prey size, presence of detritus and surgical manipulation of bill morphology. Extension of these models to five additional species predicts that interspecific variation in the foraging trade-off should result in interspecific partitioning of prey by size when detritus is present. To determine if phenotypic divergence is the result of negative interspecific interactions, I tested for a negative correlation between frequencies of interspecific aggression and phenotypic divergence. Comparison of observed frequencies to the predictions of a null model indicated aggression differed between species pairs. Divergence in body size, body length, lamellar density and divergence of species along a prey size axis predicted by the biomechanical models were all negatively correlated with frequency of aggression, even after controlling for phylogenetic distance. Variation in aggression accounted for by phenotype and phylogeny were additive, indicating ecology and evolutionary history contribute independently to species interactions. These results provide evidence that dabbling ducks represent an adaptive radiation.
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.

Download or read book Texas Waterfowl written by William P. Johnson and published by Texas A&M University Press. This book was released on 2013-01-18 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1999 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contains papers presented at a conference on sea ducks, a group of waterfowl exhibiting dramatic ornate plumages and life history strategies that are more akin to sea birds than to other species of ducks. Topics of the papers include: behaviour of harlequin ducks and scoters; productivity of breeding harlequin ducks; time budgets of surf scoter broods; habitat associations of nesting spectacled eiders; periodic non-breeding of Steller's eiders; philopatry of moulting harlequin ducks; foraging strategies and habitat use; distribution of scoters and eiders in the St. Lawrence estuary; and the eastern population of Barrow's goldeneye. Appendices include abstracts of nine other papers.
Download or read book The North American Sea Ducks written by Paul Johnsgard and published by Lulu.com. This book was released on 2016-11-09 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 21 species of sea ducks are one of the larger subgroups (Tribe Mergini) of the waterfowl family Anatidae, and the 16 species (one historically extinct) that are native to North America represent the largest number to be found on any continent, and also the largest number of endemic sea duck species native to any continent. Although generally not important as game birds, the sea ducks include some economically important birds such as the eiders, the basis for the Arctic eiderdown industry and a historically important food source for some Native American cultures. They also include what is probably the most northerly breeding species of all waterfowl and an icon of Arctic bird life, the long-tailed duck. The sea ducks also include species having some of the most complex and diverse pair-forming postural and acoustic displays of all waterfowl (goldeneyes and bufflehead), and some of the deepest diving species of all waterfowl (scoters and long-tailed duck). Sea ducks are highly prone to population disasters caused by oil spills and other water contaminants and, like other seabirds, are among the first bird groups that are being affected by current global warming trends in polar regions. This book is an effort to summarize succinctly our current knowledge of sea duck biology and to provide a convenient survey of the vast technical literature on the group, with over 900 literature references. It also includes 90,000 words of text (more than 40 percent of which is new), 15 updated range maps, 11 black & white and 20 color photographs, over 30 ink drawings, and nearly 150 sketches. Lastly, the North American sea ducks include the now extinct Labrador duck, the only northern hemisphere waterfowl species to have gone extinct in modern times. I have gratefully reprinted a Labrador duck watercolor by Sir Peter Scott. Considering recent population crashes in other sea ducks, such as the Steller's eider and spectacled eider, it should also offer a sobering reminder of the fragility of our natural world and its inhabitants, including us.
