As the study of cooperative breeding systems expands, a number of key species form the examples that underpin our general understanding. The ostrich is increasingly becoming such a textbook species, on the basis of the results obtained in Brian Bertram's study of vigilance and egg discrimination in this extraordinary bird. Here Bertram presents new data on the ostrich communal nesting system, in which several females lay in one female's nest, with only one female and the male doing all the work. The Ostrich Communal Nesting System unravels the basis of the cooperation observed, and explains how a system involving apparent altruism is maintained by natural selection. It is now possible as never before to explain and quantify the effects of the different choices these birds make and to integrate ecological and morphological factors such as predation and size. Based on three seasons of study in Tsavo West National Park in Kenya, this book depended on recognizing individual birds, detecting and monitoring well-concealed nests, determining motherhood of eggs from their surface appearance, and time-lapse photography of nests. Key findings were that females could switch rapidly between reproductive strategies, that a nesting female could recognize her own eggs and when necessary discriminate against those of other females, and that the whiteness of ostrich eggs is an adaptation that protects them against overheating but at the cost of greater vulnerability to predation. Originally published in 1992. 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.

A comprehensive review of all aspects of ostrich production including a series of case histories from some countries that farm ostriches commercially: important countries such as South Africa, Namibia and Zimbabwe; newly re-emerging industries such as Australia; and countries where production is less developed, such as Kenya, Ethiopia and the United Arab Emirates (UAE).

The Word Biblical Commentary delivers the best in biblical scholarship, from the leading scholars of our day who share a commitment to Scripture as divine revelation. This series emphasizes a thorough analysis of textual, linguistic, structural, and theological evidence. The result is judicious and balanced insight into the meanings of the text in the framework of biblical theology. These widely acclaimed commentaries serve as exceptional resources for the professional theologian and instructor, the seminary or university student, the working minister, and everyone concerned with building theological understanding from a solid base of biblical scholarship. Overview of Commentary Organization Introduction—covers issues pertaining to the whole book, including context, date, authorship, composition, interpretive issues, purpose, and theology. Each section of the commentary includes: Pericope Bibliography—a helpful resource containing the most important works that pertain to each particular pericope. Translation—the author’s own translation of the biblical text, reflecting the end result of exegesis and attending to Hebrew and Greek idiomatic usage of words, phrases, and tenses, yet in reasonably good English. Notes—the author’s notes to the translation that address any textual variants, grammatical forms, syntactical constructions, basic meanings of words, and problems of translation. Form/Structure/Setting—a discussion of redaction, genre, sources, and tradition as they concern the origin of the pericope, its canonical form, and its relation to the biblical and extra-biblical contexts in order to illuminate the structure and character of the pericope. Rhetorical or compositional features important to understanding the passage are also introduced here. Comment—verse-by-verse interpretation of the text and dialogue with other interpreters, engaging with current opinion and scholarly research. Explanation—brings together all the results of the discussion in previous sections to expose the meaning and intention of the text at several levels: (1) within the context of the book itself; (2) its meaning in the OT or NT; (3) its place in the entire canon; (4) theological relevance to broader OT or NT issues. General Bibliography—occurring at the end of each volume, this extensive bibliographycontains all sources used anywhere in the commentary.

A Publishers Weekly Best Book One of the New York Public Library's "25 Books to Remember" for 1999 Lavishly illustrated and meticulously researched, filled with fascinating facts and astonishing descriptions of animal behavior, Bruce Bagemihl's Biological Exuberance is a landmark book that will change forever how we look at nature. Homosexuality in its myriad forms has been scientifically documented in more than 450 species of mammals, birds, reptiles, insects, and other animals worldwide. Biological Exuberance is the first comprehensive account of the subject, bringing together accurate, accessible, and nonsensationalized information. Drawing upon a rich body of zoological research spanning more than two centuries, Bagemihl shows that animals engage in all types of nonreproductive sexual behavior. Sexual and gender expression in the animal world displays exuberant variety, including same-sex courtship, pair-bonding, sex, and co-parenting—even instances of lifelong homosexual bonding in species that do not have lifelong heterosexual bonding. Part 1, "A Polysexual, Polygendered World," begins with a survey of homosexuality, transgender, and nonreproductive heterosexuality in animals and then delves into the broader implications of these findings, including a valuable perspective on human diversity. Bagemihl also examines the hidden assumptions behind the way biologists look at natural systems and suggests a fresh perspective based on the synthesis of contemporary scientific insights with traditional knowledge from indigenous cultures. Part 2, "A Wondrous Bestiary," profiles more than 190 species in which scientific observers have noted homosexual or transgender behavior. Each profile is a verbal and visual "snapshot" of one or more closely related bird or mammal species, containing all the documentation required to support the author's often controversial conclusions.
