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 324 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 Birdtalk written by Alan Powers and published by Frog Books. This book was released on 2003 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the last 20 years, Alan Powers, who lives near Cape Cod, has experimented with birdcalls--mimicking and answering the calls he hears around his country home, in cities, and abroad in France and Italy. In BirdTalk, he celebrates this connection with entertaining allusions to history, literature, travel, linguistics, and other fields. The result is a charming and erudite stroll through an area of interest sometimes lost in the urban din. Powers reveals "birdtalk" by mapping the history of ornithological studies, quoting such bird fanciers as Shakespeare and Emily Dickinson and discussing specific techniques. In one of the most amusing chapters, he describes his attempts to teach the birds new symphonic riffs on their own calls. This illustrated literary inquiry into birdcalls is a nature book with a gift-book look.
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.

Available in PDF, EPUB and Kindle. Book excerpt: Birdsong made easy to understand, lavishly illustrated with color photos, and accompanied by more than 700 online recordings From a leading expert, Birdsong for the Curious Naturalist is a basic, how-to guide that teaches anyone--from beginner to advanced birder--how to listen. In understandable and appealing language, Kroodsma explains why and how birds sing, what various calls mean, and what to listen for from the birds around us. The descriptions are accompanied by color photos of the birds, as well as QR codes that link to an online collection of more than 700 recordings. With these resources, readers are prepared to recognize bird sounds and the birds that make them. Kroodsma encourages readers to find the joy of birdsong and curiosity--to observe, listen intently, be curious, ask questions, and realize that many unanswered questions about birdsong don't have to rely on scientists for answers but can be answered by any curious naturalist.
Download or read book Sibley s Birding Basics written by David Allen Sibley and published by Knopf. This book was released on 2008-12-18 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the renowned author of the New York Times best seller The Sibley Guide to Birds, a comprehensive, beautifully illustrated guide to identifying birds in the field. Sibley's Birding Basics is an essential companion for birders of all skill and experience levels. With Sibley as your guide, learn how to interpret what the feathers, the anatomical structure, the sounds of a bird tell you. When you know the clues that show you why there’s no such thing as, for example, “just a duck” birding will be more fun, and more meaningful. An essential addition to the Sibley shelf! The Sibley Guide to Birds and The Sibley Guide to Bird Life and Behavior are both universally acclaimed as the new standard source of species information. And now David Sibley, America’s premier birder and best-known bird artist, turns his attention to the general characteristics that influence the appearance of all birds, unlocking the clues to their identity. In 200 beautifully rendered illustrations and 16 essays, this scientifically precise volume distills the essence of Sibley’s own experience and skills, providing a solid introduction to “naming” the birds. Birding Basics reviews how one can get started as a birder—the equipment necessary, where and when to go birding, and perhaps most important, the essential things to look for when birds appear in the field—as well as the basic concepts of bird identification and the variations that can change the appearance of a bird over time or in different settings. Sibley also provides critical information on the aspects of avian life that differ from species to species: feathers (color, arrangement, shape, molt), behavior and habitat, and sounds.

Download or read book Peterson Field Guide to Bird Sounds of Western North America written by Nathan Pieplow and published by Houghton Mifflin Harcourt. This book was released on 2019-04-02 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive field guide that uses an innovative Sound Index to allow readers to quickly identify unfamiliar songs and calls of birds in western North America. Bird songs and calls are at least as important as visual field marks in identifying birds. Yet short of memorizing each bird’s repertoire, it’s difficult to sort through them all. Now, with the western edition of this groundbreaking book, it’s possible to visually distinguish bird sounds and identify birds using a field-guide format. At the core of this guide is the spectrogram, a visual graph of sound. With a brief introduction to five key aspects—speed, repetition, pauses, pitch pattern, and tone quality—readers can translate what they hear into visual recognition, without any musical training or auditory memorization. The Sound Index groups similar songs together, narrowing the identification choices quickly to a brief list of birds that are likely to be confused because of the similarity of their songs. Readers can then turn to the species account for more information and/or listen to the accompanying audio tracks available online. Identifying birds by sound is arguably the most challenging and important skill in birding. This book makes it vastly easier to master than ever before.
Download or read book Advances in the Study of Behavior written by and published by Elsevier. This book was released on 2002-01-21 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of Advances in the Study of Behavior remains as it has been since the series began: to serve the increasing number of scientists who are engaged in the study of animal behavior by presenting their theoretical ideas and research to their colleagues and to those in neighboring fields. We hope that the series will continue its "contribution to the development of the field", as its intended role was phrased in the Preface to the first volume in 1965. Since that time, traditional areas of animal behavior have achieved new vigor by the links they have formed with related fields and by the closer relationship that now exists between those studying animal and human subjects.Advances in the Study of Behavior, Volume 31 continues to serve scientists across a wide spectrum of disciplines. Focusing on new theories and research developments with respect to behavioral ecology, evolutionary biology, and comparative psychology, these volumes foster cooperation and communications in these dense fields.
