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.

Book Synopsis Orioles, Blackbirds, and Their Kin by : Alexander F. Skutch
Download or read book Orioles, Blackbirds, and Their Kin written by Alexander F. Skutch and published by University of Arizona Press. This book was released on 2021-10-19 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: From blackbirds and orioles to meadowlarks, grackles, and cowbirds, the variety and variation shown by members of the family Icteridae is legend. The family exhibits great diversity in size and coloration, mating and nest building, and habits and habitats. This group of 94 New World species once known as the troupials is well represented in backyards across America; yet most icterids are tropical or semi-tropical species that remain largely unstudied. The least known of these species are perhaps best known to Alexander Skutch, who has studied birds in a Costa Rican tropical valley for more than half a century. In this fascinating book the first devoted exclusively to the icterids—he combines his own observations with those of other naturalists to provide a comparative natural history and biology of this remarkable family of birds. Devoting a separate chapter to each major group or genus, he delineates the outstanding characteristics of each and includes observations of little-studied tropical species such as caciques and oropendolas. Orioles, Blackbirds, and Their Kin is an eminently readable natural history in the classic style. Enhanced by 31 scratchboard illustrations, this book will delight nature enthusiasts everywhere with its fascinating exposition of avian diversity. Because so much of the published information on the icterids is widely scattered, Skutch's painstaking compilation has created a valuable reference work that will provide students and researchers with a wealth of new insights into the tropical members of this New World family.

Book Synopsis Red-winged Blackbirds by : Les D. Beletsky
Download or read book Red-winged Blackbirds written by Les D. Beletsky and published by University of Chicago Press. This book was released on 1996 with total page 328 pages. 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 Synopsis Ecology and Management of Blackbirds (Icteridae) in North America by : George M. Linz
Download or read book Ecology and Management of Blackbirds (Icteridae) in North America written by George M. Linz and published by CRC Press. This book was released on 2017-09-19 with total page 311 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.

Book Synopsis Ecology and Management of Cowbirds and Their Hosts by : James N. M. Smith
Download or read book Ecology and Management of Cowbirds and Their Hosts written by James N. M. Smith and published by University of Texas Press. This book was released on 2014-09-05 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past two centuries, cowbirds have increased in numbers and extended their range across North America, while many of the native songbird species whose nests they parasitize to raise their young have declined. This timely book collects forty essays by most of the principal authorities on the biology and management of cowbirds. The book's goals are to explore the biology of cowbirds, the threats they pose to host species and populations, and the management programs that are being undertaken to minimize these threats. The book is organized into five sections, each with an extended editors' introduction that places the contributions in a broad, up-to-date setting. The sections cover: The changing abundance of cowbirds and the ways in which their numbers can be estimated. Host choice by cowbirds, the negative effects of cowbirds on particular host species, and the daily patterns of cowbird behavior. Behavioral interactions between cowbirds and specific host species. Patterns of cowbird abundance and host use across varying landscapes. Management programs designed to control cowbirds and protect threatened songbirds.

Book Synopsis Polygyny and Sexual Selection in Red-Winged Blackbirds by : William A. Searcy
Download or read book Polygyny and Sexual Selection in Red-Winged Blackbirds written by William A. Searcy and published by Princeton University Press. This book was released on 2014-07-14 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to explain why red-winged blackbirds are polygynous and to describe the effects of this mating system on other aspects of the biology of the species. Polygyny is a mating system in which individual males form long-term mating relationships with more than one female at a time. The authors show that females choose to mate polygynously because there is little cost to sharing male parental care in this species, and because females gain protection against nest predation by nesting near other females. Polygyny has the effect of intensifying sexual selection on males by increasing the variance in mating success among males. For females, polygyny means that they will often share a male's territory with other females during the breeding season and will thus be forced to adapt to frequent female-female interactions. This work reviews the results of many studies by other researchers, as well as presenting the authors' own results. Studies of red-winged blackbirds have ranged from long-term investigations of reproductive success and demography, to research on genetic parentage based on modern molecular methods, to a variety of experimental manipulations of ecological circumstances and behavior. Since the red-winged blackbird is one of the best studied species of any taxa in terms of its behavior and ecology, the authors have a particularly extensive body of results on which to base their conclusions.

Book Synopsis Neotropical Migratory Birds by : Richard DeGraaf
Download or read book Neotropical Migratory Birds written by Richard DeGraaf and published by Cornell University Press. This book was released on 2019-06-07 with total page 699 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thrushes, warblers, vireos, and tanagers are probably the most familiar of the Neotropical migrants—birds that breed in the United States and Canada, then journey to spend the winter in the Caribbean, Mexico, or southward. But this extraordinary group actually comprises a large number of diverse species, including waterfowl, shorebirds, terns, hawks, flycatchers, and hummingbirds. In their compendious review of information on these birds, Richard M. DeGraaf and John H. Rappole illuminate the need for a thorough understanding of the ecology of each species, one that exte4nds throughout the entire life cycle. The authors argue convincingly that conservation efforts must be based on such an understanding and carried out across a species' range—not limited to the breeding grounds. This book is the first to summarize in one volume much-needed practical data about the distribution and breeding habitat requirements of migratory birds in North and South America. The body of the book consists of natural history accounts of more than 350 species of Neotropical migrants, including a brief description of each bird's range, status, habitats on breeding grounds, nest site, and wintering areas. The authors provide a complete range map of each species' distribution in the Western Hemisphere as well as notes on the distribution—basic data that until recently have largely been unavailable in usable form to ornithologists and land and resource managers. An appendix lists species that are increasing or decreasing at significant rates in various physiographic regions of North America.
