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.

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.

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

Just over one hundred and thirty years ago Charles Darwin, in The Descent of Man and Selection in Relation to Sex (1871), developed remarkably accurate conclusions about man's ancestry, based on a review of general comparative anatomy and psychology in which he regarded sexual selection as a necessary part of the evolutionary process. But the attention of biologists turned to the more general concept of natural selection, in which sexual selection plays a complex role that has been little understood. This volume significantly broadens the scope of modern evolutionary biology by looking at this important and long neglected concept of great importance. In this book, which is the first full discussion of sexual selection since 1871, leading biologists bring modern genetic theory and behavior observation to bear on the subject. The distinguished authors consider many aspects of sexual selection in many species, including man, within the context of contemporary evolutionary theory and research. The result is a remarkably original and well-rounded view of the whole concept that will be invaluable especially to students of evolution and human sexual behavior. The lucid authority of the contributors and the importance of the topic will interest all who share in man's perennial fascination with his own history. The book will be of central importance to a wide variety of professionals, including biologists, anthropologists, and geneticists. It will be an invaluable supplementary text for courses in vertebrate biology, theory of evolution, genetics, and physical anthropology. It is especially important with the emergence of alternative explanations of human development, under the rubric of creationism and doctrines of intelligent design.

With more than 10,000 species that vary in size, use diverse habitats that extend across latitudes and altitudes, consume a wide variety of food items, differ in how they fly (or not), communicate, and reproduce, and have different life histories, birds exhibit remarkable variation in form (anatomy) and function (physiology). Our understanding of how natural selection has generated this variation as birds evolved and as different species adapted to their unique circumstances has grown considerably in recent years. In In a Class of Their Own: A Detailed Examination of Avian Forms and Functions, this variation is explained in great detail, beginning with an overview of avian evolution and continuing with information about the structure and function of the avian skeleton, muscles, and the various body systems. Other chapters focus on avian locomotion (including flight), migration, navigation, communication, energy balance and thermoregulation, and various aspects of avian reproduction, such as nests and nest building, clutch sizes, and parental care. In a Class of Their Own: A Detailed Examination of Avian Forms and Functions will be must reading for anyone, professional or non-professional, who needs or wants to learn more about birds.

Beginning with Darwin's work in the 1870s, Foundations of Animal Behavior selects the most important works from the discipline's first hundred years—forty-four classic papers—and presents them in facsimile, tracing the development of the field. These papers are classics because they either founded a line of investigation, established a basic method, or provided a new approach to an important research question. The papers are divided into six sections, each introduced by prominent researchers. Sections one and two cover the origins and history of the field and the emergence of basic methods and approaches. They provide a background for sections three through six, which focus on development and learning; neural and hormonal mechanisms of behavior; sensory processes, orientation, and communication; and the evolution of behavior. This outstanding collection will serve as the basis for undergraduate and graduate seminars and as a reference for researchers in animal behavior, whether they focus on ethology, behavioral ecology, comparative psychology, or anthropology.
