New World Blackbirds is a comprehensive guide to the 103 members of the family Icteridae, also known as the icterids or troupials. The icterids are a diverse family, ranging throughout the Americas from Alaska to the Caribbean and south to Cape Horn. Despite the name "blackbird," the group contains such highly colored birds as the orioles. It includes common and intensively studied species--the Red-winged Blackbird and the Brown-headed Cowbird, for example--and such rare and obscure birds as the Colombian Mountain-Grackle and the Montserrat and Martinique Orioles. Two species in the family, the Selva Cacique and the Pale-eyed Blackbird, were not described at all until as recently as the 1960s and 1970s. The thirty-nine highly detailed plates in this book depict all the species and many subspecies and age types never illustrated before. The book also contains over one hundred color range maps as well as black-and-white illustrations to aid identification. The extensive text summarizes the characteristics and natural history of each species, giving details on behavior, nesting, geographic variation, distribution, vocalizations, and in-depth plumage descriptions for all age types. Clearly written and exhaustively researched, this book will be the standard reference work for this major family of birds.

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.

The variety of social systems among the New World blackbirds (Family Icteridae) and the structural simplicity of their foraging environment provide excellent opportunities for testing theorics about the adaptive significance of their behavior. Here Gordon Orians presents the results of his many years of research on how blackbirds utilize their marsh environments during the breeding season. These results stem from information he gathered on three species during ten breeding seasons in the Pacific Northwest, on Red-winged blackbirds during two breeding seasons in Costa Rica, and on three species during one breeding season in Argentina. The author uses models derived from Darwin's theory of natural selection to predict the behavior and morphology of individuals as well as the statistical properties of their populations. First he tests models that predict habitat selection, foraging behavior, territoriality, and mate selection. Then he considers some population patterns, especially range of use of environmental resources and overlap among species, that may result from those individual attributes. Professor Orianns concludes with an overview of the structure of bird communities in marshes of the world and the relation of these patterns to overall source availability in these simple but productive habitats.

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.

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.
