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.

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.

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 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

This book was released on 2013 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Red-winged blackbird reproduction in stormwater ponds in an urban and suburban landscape: evidence for ecological traps Ecological traps develop when organisms prefer a sink habitat over an available source habitat. Following best management practices, stormwater ponds are created to alleviate effects of increased impervious surfaces in areas of urbanization such as decreases in groundwater recharge. However, given their tendency to attract wildlife, organisms that use these habitats can become exposed to greater than normal levels of pollutants. Additionally, pond structure can attract a diversity of wildlife to the pond, including an assortment of predators, which can cause decreases in reproductive success. I surveyed breeding Red-winged Blackbird populations in a suburban and urban landscape to determine stormwater ponds' potential role as an ecological trap. I suggest that stormwater ponds in suburban landscapes are serving as sink habitats for Red-winged Blackbirds due to high rates of predation, and may potentially act as ecological traps if preferentially selected, while urban landscapes may support Red-winged Blackbirds.
