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.

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.

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.

This book is a comprehensive study of nest-building behavior in birds. A much-needed synthesis of the previously scattered literature on this central aspect of avian biology, it is organized by behavior problems and focuses on evolution as its unifying theme. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This volume is a synthesis of existing knowledge about the flora and fauna of Costa Rica. The major portion of the book consists of detailed accounts of agricultural species, vegetation, amphibians, reptiles, mammals, birds, and insects. "This is an extraordinary, virtually unique work. . . . The tremendous amount of original, previously unpublished, firsthand information is remarkable."—Peter H. Raven, Director, Missouri Botanical Garden "An essential resource for anyone interested in tropical biology. . . . It can be used both as an encyclopedia—a source of facts on specific organisms—and as a source of ideas and generalizations about tropical ecology."—Alan P. Smith, Ecology
