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.

Raphael’s Ostrich begins with a little-studied aspect of Raphael’s painting—the ostrich, which appears as an attribute of Justice, painted in the Sala di Costantino in the Vatican. Una Roman D’Elia traces the cultural and artistic history of the ostrich from its appearances in ancient Egyptian hieroglyphs to the menageries and grotesque ornaments of sixteenth-century Italy. Following the complex history of shifting interpretations given to the ostrich in scientific, literary, religious, poetic, and satirical texts and images, D’Elia demonstrates the rich variety of ways in which people made sense of this living “monster,” which was depicted as the embodiment of heresy, stupidity, perseverance, justice, fortune, gluttony, and other virtues and vices. Because Raphael was revered as a god of art, artists imitated and competed with his ostrich, while religious and cultural critics complained about the potential for misinterpreting such obscure imagery. This book not only considers the history of the ostrich but also explores how Raphael’s painting forced viewers to question how meaning is attributed to the natural world, a debate of central importance in early modern Europe at a time when the disciplines of modern art history and natural history were developing. The strangeness of Raphael’s ostrich, situated at the crossroads of art, religion, myth, and natural history, both reveals lesser-known sides of Raphael’s painting and illuminates major cultural shifts in attitudes toward nature and images in the Renaissance. More than simply an examination of a single artist or a single subject, Raphael’s Ostrich offers an accessible, erudite, and charming alternative to Vasari’s pervasive model of the history of sixteenth-century Italian art.

Dragons, unicorns, mermaids... all the famous creatures of myth and legend are to be found in the Torah, Talmud and Midrash. But what are we to make of them? Do they really exist? Did the Torah scholars of old believe in their existence? And if not, why did they describe these creatures? Sacred Monsters is a thoroughly revised and vastly expanded edition of the bestselling book Mysterious Creatures. Rabbi Natan Slifkin, the famous "Zoo Rabbi," revisits all the creatures of that work as well as a host of new ones, including werewolves, giants, dwarfs, two-headed mutants, and the enigmatic shamir-worm. Sacred Monsters explores these cases in detail and discusses a range of different approaches for understanding them. Aside from the fascinating insights into these cryptic creatures, Sacred Monsters also presents a framework within which to approach any conflict between classical Jewish texts and the modern scientific worldview. Complete with extraordinary photographs and fascinating ancient illustrations, Sacred Monsters is a scholarly yet stimulating work that will be a treasured addition to your bookshelf

This volume reviews, for the first time, the broad range of issues that affect the welfare of commercially farmed ratites. Although ratites incorporate several families of flightless birds this book focuses on the most commonly farmed ratites, the ostrich, emu and rhea. The readers are taken on a journey through all sectors of the industry, which include breeding, incubation, hatching, brooding, rearing, growth, transport and processing, with an emphasis on husbandry and management protocols that can impact bird welfare and health. Also discussed is the structure and sensory innervation of the skin and digits of the birds, and the potential welfare implications of industry practices on these structures. Each chapter in this volume focuses on a particular aspect of the commercial farming of ratites with contributing authors from a broad range of disciplines.
