This book was released on 2020-03-31 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The variety of social systems among the New World blackbirds (Family Icteridae) and the structural simplicity of their foraging environment provide excellent opportunities for testing theorics about the adaptive significance of their behavior. Here Gordon Orians presents the results of his many years of research on how blackbirds utilize their marsh environments during the breeding season. These results stem from information he gathered on three species during ten breeding seasons in the Pacific Northwest, on Red-winged blackbirds during two breeding seasons in Costa Rica, and on three species during one breeding season in Argentina. The author uses models derived from Darwin's theory of natural selection to predict the behavior and morphology of individuals as well as the statistical properties of their populations. First he tests models that predict habitat selection, foraging behavior, territoriality, and mate selection. Then he considers some population patterns, especially range of use of environmental resources and overlap among species, that may result from those individual attributes. Professor Orianns concludes with an overview of the structure of bird communities in marshes of the world and the relation of these patterns to overall source availability in these simple but productive habitats.

This book was released on 2017-09-19 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shortlisted for the 2018 TWS Wildlife Publication Awards in the edited book category The various species of new world blackbirds, often intermingled in large foraging flocks and nighttime roosts, collectively number in the hundreds of millions and are a dominant component of the natural and agricultural avifauna in North America today. Because of their abundance, conspicuous flocking behavior, and feeding habits, these species have often been in conflict with human endeavors. The pioneering publications on blackbirds were by F. E. L. Beal in 1900 and A. A. Allen in 1914. These seminal treatises laid the foundation for more than 1,000 descriptive and experimental studies on the life histories of blackbirds as well as their ecology and management in relation to agricultural damage and other conflicts such as caused by large winter roosting congregations. The wealth of information generated in over a century of research is found in disparate outlets that include government reports, conference proceedings, peer-reviewed journals, monographs, and books. For the first time, Ecology and Management of Blackbirds (Icteridae) in North America summarizes and synthesizes this vast body of information on the biology and life histories of blackbirds and their conflicts with humans into a single volume for researchers, wildlife managers, agriculturists, disease biologists, ornithologists, policy makers, and the public. The book reviews the life histories of red-winged blackbirds, yellow-headed blackbirds, common grackles, and brown-headed cowbirds. It provides in-depth coverage of the functional roles of blackbirds in natural and agricultural ecosystems. In doing so, this authoritative reference promotes the development of improved science-based, integrated management strategies to address conflicts when resolutions are needed.

Available in PDF, EPUB and Kindle. Book excerpt: Drawing on detailed data from their sixteen-year study of red-winged blackbirds in the marshes of Washington's Columbia National Wildlife Refuge, Beletsky and Orians analyze the information redwings use to make breeding-season decisions and the consequences these decisions have for lifetime reproductive success. Because male and female redwings make different, and often independent, decisions—males focus on territory acquisition and maintenance, while females must choose when and where to nest and how much energy to invest in reproduction—the authors have taken the novel approach of studying the sexes separately. Using analyses of observational data combined with field experiments and game-theoretical models, the authors provide new insights into the complex patterns of reproductive decision-making and breeding behavior in redwings. This book will be of interest to all who study social animals, including behavioral ecologists, evolutionary biologists, and ornithologists.

Book excerpt: The Red-winged Blackbird is not only one of North America's commonest birds, but also its best studied. It exemplifies the contribution that in-depth species studies can make to many of the central issues in behavioral ecology. In this book, Les Beletsky calls on 20 years experience of redwings to provide an up-to-date, comprehensive summary of all the major work done with these birds. These studies on the redwings' polygynous breeding system, strong territoriality, complex vocal communications, and broad distribution shed light on many themes of key interest to behaviorists and ecologists interested in the evolution of mate choice and species adaptations to habitats which vary in character in different parts of their range. An extra dimension is added in the consideration of redwings as pests, a widespread and often serious problem in crops of rice and corn. This book is written in an easy style, and will serve as an introduction, to both student and layperson, to redwings and what they can teach us of behavioral ecology. The Red-winged Blackbird provides the research worker with a balanced summary and comprehensive bibliography of one of ornithology's widest and deepest studies. Key Features * Covers perhaps the most studied bird in North America * Presents model species for studies in mating systems, habitat selection, vocal communication, and territorial behavior * Includes a comprehensive bibliography * Presented in an accessible style, ideal for student use

This book was released on 2014-07-14 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seeking common principles of social evolution in different taxonomic groups, the contributors to this volume discuss eighteen groups of birds and mammals for which long-term field studies have been carried out. They examine how social organization is shaped by the interaction between proximate ecological pressures and culture"--the social traditions already in place and shaped by local and phylogenetic history.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Red-Winged Blackbird: A Study in the Ecology of a Cat Tail Marsh The cat-tail marsh, which is here considered, is as peculiar and distinctive as any environment available for study. Great expanses of sedge, rush, and cat-tail conceal an assem blage of birds which are as interesting as they are little known birds that are little known because of the difficulties in their study, that are seldom seen because of their secretive habits, yet withal, birds that are as unique in their adaptations, as varied in their structure and habits, as any other similar group. There are the Rails, the Coot, and the Gallinule constituting an ecological unit in themselves, the Marsh Wren, Swamp Sparrow, and Red-winged Blackbird another, the Least and American Bitterns, and the Pied-billed Grebe still others. All are strictly marsh birds which seem to find their optimum environment in the cat-tail marsh. With some of these birds, adaptation to a marsh life is very evident, but with others, it is quite obscure. The long legs of the Virginia Rail for wading, the long toes for grasping the floating debris and distributing the weight, the long bill for probing, the color, the compressed shape - like that of a flea - for slipping through the dense vegetation, are decided specializations for a life in this peculiar environment. The Swamp Sparrow and the Redwing, on the other hand, show no striking modifications. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
