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.

Download or read book Avian Brood Parasitism written by Manuel Soler and published by Springer. This book was released on 2018-05-02 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brood parasitism has become one of the most flourishing areas of research in evolutionary ecology and one of the best model systems for investigating coevolution. This subject has undergone remarkable advances during the last two decades, but has not been covered by any book in the 21st century. This book offers a comprehensive and up-to-date overview of the fascinating field of avian brood parasitism. The topics covered include conspecific brood parasitism; evolution and phylogenetic history of avian brood parasites; parasitic behaviour used by brood parasites; adaptations and counter-adaptations of brood parasites and their hosts at every stage of the breeding cycle (before laying, egg, chick and fledgling stages); factors affecting the evolution of host defences and parasitic attacks; the role of phenotypic plasticity in host defences; mechanisms driving egg recognition and rejection; evolution of nest sharing or nest killing by brood parasite chicks; begging behaviour in parasitized nests and food delivery by host adults; and recognition of conspecifics by juvenile brood parasites. This volume provides a comprehensive reference resource for readers and researchers with an interest in birds, behaviour and evolution, as well as a source of hypotheses and predictions for future investigations into this dynamic subject.

Download or read book Current Ornithology Volume 17 written by Charles F. Thompson and published by Springer Science & Business Media. This book was released on 2010-09-09 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.

Download or read book Parasitic Birds and Their Hosts written by Stephen I. Rothstein and published by Oxford University Press on Demand. This book was released on 1998 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first to present a comprehensive overview of parasitic birds and their hosts. Although the phenomenon has attracted the interest of naturalists and evolutionists since Darwin, only recently have researchers applied modern evolutionary theory and experimental methods to study the various adaptations related to brood parasitism. The work in this field is accelerating rapidly, and this volume collects work from the individuals and research groups around the world who have been responsible for nearly every major study in the last ten years. The papers present valuable summaries along with substantial new research, and the volume concludes with a review of important unsolved questions. The book is an invaluable resource on this fascinating topic, covering the remarkable sequences of adaptations and counter-adaptations, along with the perhaps even more remarkable cases where adaptations seem to be lacking.

Download or read book The Book of Eggs written by Mark E. Hauber and published by University of Chicago Press. This book was released on 2014-08-01 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the brilliantly green and glossy eggs of the Elegant Crested Tinamou—said to be among the most beautiful in the world—to the small brown eggs of the house sparrow that makes its nest in a lamppost and the uniformly brown or white chickens’ eggs found by the dozen in any corner grocery, birds’ eggs have inspired countless biologists, ecologists, and ornithologists, as well as artists, from John James Audubon to the contemporary photographer Rosamond Purcell. For scientists, these vibrant vessels are the source of an array of interesting topics, from the factors responsible for egg coloration to the curious practice of “brood parasitism,” in which the eggs of cuckoos mimic those of other bird species in order to be cunningly concealed among the clutches of unsuspecting foster parents. The Book of Eggs introduces readers to eggs from six hundred species—some endangered or extinct—from around the world and housed mostly at Chicago’s Field Museum of Natural History. Organized by habitat and taxonomy, the entries include newly commissioned photographs that reproduce each egg in full color and at actual size, as well as distribution maps and drawings and descriptions of the birds and their nests where the eggs are kept warm. Birds’ eggs are some of the most colorful and variable natural products in the wild, and each entry is also accompanied by a brief description that includes evolutionary explanations for the wide variety of colors and patterns, from camouflage designed to protect against predation, to thermoregulatory adaptations, to adjustments for the circumstances of a particular habitat or season. Throughout the book are fascinating facts to pique the curiosity of binocular-toting birdwatchers and budding amateurs alike. Female mallards, for instance, invest more energy to produce larger eggs when faced with the genetic windfall of an attractive mate. Some seabirds, like the cliff-dwelling guillemot, have adapted to produce long, pointed eggs, whose uneven weight distribution prevents them from rolling off rocky ledges into the sea. A visually stunning and scientifically engaging guide to six hundred of the most intriguing eggs, from the pea-sized progeny of the smallest of hummingbirds to the eggs of the largest living bird, the ostrich, which can weigh up to five pounds, The Book of Eggs offers readers a rare, up-close look at these remarkable forms of animal life.
