Download or read book The Red winged Blackbird written by Les Beletsky and published by . This book was released on 1996 with total page 332 pages. Available in PDF, EPUB and Kindle. 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

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.

Download or read book Phylogenies and the Comparative Method in Animal Behavior written by Emília P. Martins and published by Oxford University Press, USA. This book was released on 1996 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last ten years, the "comparative method" has been revolutionized by modern statistical ways of incorporating phylogenies into the design and analysis of comparative studies. The results of this revolution are particularly important in the study of animal behavior, which has relied on interspecific comparisons to infer universal trends and evolutionary patterns. The chapters of this edited volume consider the impact of modern phylogenetic comparative methods on the study of animal behavior and discuss the main issues that need to be considered in design and analysis of a comparative study, considers possible differences between the evolution of behavior and the evolution of morphology, and reviews how phylogenetic comparative studies have been used in certain areas of behavioral research.
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.

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.
Download or read book Current Ornithology written by D.M. Power and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited series has three principal goals. The first is to provide information in a relatively concise way for researchers needing an over view of specific disciplines. The second is to provide an update on specific schools of thought, bringing together ideas from colleagues whose works often appear in a variety of journals. And the third is to stimulate and suggest directions for new research. Volume 6 continues the tradition established by the previous editor and editorial board in providing new information, updating our understanding of specific dis ciplines, and stimulating new research. In the first chapter, Randall Breitwisch examines mortality patterns and sex ratios in monogamous birds. He argues that there are many more components to measuring parental investment than are often re alized; our knowledge is weak in several areas. Understanding the evo lution of mating systems depends on better distinguishing the different intensities of natural selection that operate on males and females. Greg ory Butcher and Sievert Rohwer develop a framework for assessing the role of colorfulness in birds. They propose several hypotheses to test and advocate evaluating more than one hypothesis at a time. Future work on the evolution of distinctive coloration and of sexual and age dimorphism must take these ideas into account.

Download or read book Woodcock Status Report 1965 written by William H. Goudy and published by . This book was released on 1966 with total page 1194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Singing-ground surveys of the American woodcock indicate that breeding populations have increased gradually over the past 7 years while production, as indicated by wing-collection surveys, has remained relatively stable. The woodcock harvest, meanwhile, has probably more than doubled during the past decade. This suggests that while woodcock are probably becoming more important to North American sportsmen, hunting mortality is still relatively unimportant.
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.

Download or read book The Behavior of Communicating written by William John. Smith and published by Harvard University Press. This book was released on 2009-06-30 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, W. John Smith enlarges ethology's perspective on communication and takes it in new directions. Traditionally, ethological analysis has focused on the motivational states of displaying animals: What makes the bird sing, the cat lash its tail, the bee dance? The Behavior of Communicating emphasizes messages. It seeks to answer questions about the information shared by animals through their displays: What information is made available to a bird by its neighbor's song, to a cat by its opponent's gesture, to a bee by its hivemate's dancing? What information is extracted from sources contextual to these displays? How are the responses to displays adaptive for recipients and senders? What evolutionary processes and constraints underlie observed patterns of animal communication? Smith's approach is deeply rooted in the ethological tradition of naturalistic observations. Detailed analysis of observed displays and display repertoires illuminates the theoretical discussion that forms the core of the book. A taxonomy and interpretative analysis of messages made available through formalized display behavior are also developed. Smith shows that virtually all subhuman animal displays may be interpreted as transmitting messages about the communicator--not the environment--and, more specifically, that messages indicate the kinds of behavior the displaying animal may choose to perform. The most widespread behavioral messages are surprisingly general, even banal, in character; yet they make public information that is not readily available from other sources and that would otherwise be essentially private to the communicator. Taken along with information from sources contextual to the displays, the messages made available may permit responses that are markedly specific. By taking advantage of contextual specificity, a species expands the capacity of its display behavior to be functional in numerous and diverse circumstances. After developing the concept of messages and discussing their forms, the responses made to them, and the functions engendered, Smith turns to the evolution of display behavior--the ways in which acts become specialized for communication and the nature of the evolutionary constraints affecting the ultimate forms of displays. He revises the traditional ethological concept of displays, and in a final chapter develops the further concept of formalized interactions. Here he extends the discussion to formal patterns of behavior that, unlike displays, are beyond the capabilities of individual performers. Human nonverbal communication, which is considered from time to time throughout the book, provides the richest examples of communication flexibly structured at this level of complexity.
