From Eared Grebes, Tundra Swans, and Peregrine Falcons to Lesser Yellowlegs, and Snowy Owls, Pennsylvania is home to a magnificent array of birds. In the first comprehensive summary and analysis in over a century of the birds of that state, Gerald M. McWilliams and Daniel W. Brauning provide a wealth of information for both the professional ornithologist and the amateur birder. This book treats all 428 species seen in the state, including breeding and wintering birds, migrants, and vagrants. Each entry provides the general status of a species; the locations where it is most commonly found; its natural habitat, migratory patterns, breeding habits, and seasonal status and distribution; and a summary of the bird's history in Pennsylvania. With clear descriptions of physiographic regions as well as 44 breeding distribution maps for the most commonly seen birds and 67 photographs of many rare and hard-to-find species, this volume is an indispensable resource about Pennsylvania's bird life.
Aristophanes was clearly anxious about the role of the sophists and the “new” education in Athens. After the perceived failure of Clouds in 423 and its subsequent, unperformed revision, Aristophanes, this book argues, returned in 414 with Birds, a continuation and deepening of his critique found in Clouds. Peisetaerus or “persuader of his comrades,” the protagonist of Birds, though an old man, is clearly a student of Socrates’ phrontisterion. Unlike Socrates, however, he is political and ambitious and he understands the whole of human nature, both rational and irrational. Peisetaerus employs the various deconstructive techniques of Socrates and his allies (which is summed up on the comic sage in the image of “father-beating”) to overturn not just human society, but, with the help of his new allies, the divine and musical birds, the cosmos. After his new gods and bird city, Cloudcuckooland, are actually established, however, the hero re-introduces the “old” ways - justice, moderation, and obedience to law – but now under his personal authority, and thereby becomes “the highest of the gods.” Thus, the author postulates, in 414 Aristophanes has come to acknowledge the potency of the apparent civic-minded turn (or element) of the sophists, while aware of the self-aggrandizing nature of their ambition. Peisetaerus, unlike Socrates, is successful: he is establishing a just polis and cosmos and, therefore, must be victorious. But the consequence or cost of this success is illustrated through the Bird Chorus. After the polis is founded, the birds never again sing of their musical reciprocity with the Muses, the source of melodies for men. The birds are now political and the policemen of human beings. The sophist-run cosmos has lost its music. The new Zeus is an ugly bird-mutant. The gods and all nomoi have lost their beauty, honor, and reverential nature. Birds, in its finale, hilariously, but boldlyilluminates the inherent tension between philosophy (reason) and poetry (divinely-inspired tradition).

A comprehensive guide to all 1,817 species found in Peru—one fifth of the world's birds--with subspecies, sexes, age classes, and morphs fully illustrated Designed especially for field use, with vivid descriptive information and helpful identification tips opposite color plates Detailed species accounts, including a full-color distribution map Includes 25 additional species not covered in the first edition Features 3 entirely new plates and more than 25 additional illustrations
This book presents a comprehensive survey of perceptual expertise in visual object recognition, and introduces a novel collaborative model, codified as the "Perceptual Expertise Network" (PEN). This unique group effort is focused on delineating the domain-general principles of high-level visual learning that can account for how different object categories are processed and come to be associated with spatially localized activity in the primate brain. PEN's approach brings together different traditions and techniques to address questions such as how expertise develops, whether there are different kinds of experts, whether some disorders such as autism or prosopagnosia can be understood as a lack or loss of expertise, and how conceptual and perceptual information interact when experts recognize and categorize objects. The research and results that have been generated by these questions are presented here, along with a variety of other questions, background information, and extant issues that have emerged from recent studies, making this book a complete overview on the topic.
The development of the Thai-American alliance from 1947 to 1958 dramatically transformed both countries' involvement in Southeast Asia. Bounded by two important political events in Thailand, an army coup in 1947 and the military's assumption of complete control of government in 1958, the period witnessed both the entrenchment of authoritarian military government in Thailand and a revolution in U.S.-Thai relations. During these years the modern Thai political system emerged, and the United States established its interest and influence in mainland Southeast Asian affairs. The developments of the period made possible American's later, more extensive, involvement in Indochina. A Special Relationship provides the most comprehensive analysis of this critical founding period of the Thai-American alliance. It reveals surprising new information on joint covert operations in Indochina, American support for suppression of government opponents, and CIA involvement in Thai domestic politics.

At a time when the environment is of growing concern to students and general readers, nature writing is especially meaningful. This book profiles the literary careers of 52 early American nature writers, such as John James Audubon, Ralph Waldo Emerson, Caroline Stansbury Kirkland, Thomas Jefferson, Henry David Thoreau, and Mabel Osgood Wright. Each entry is written by an expert contributor and discusses the writer's life and works. Entries close with primary and secondary bibliographies, and the encyclopedia ends with suggestions for further reading. Global warming, pollution, and other issues have made the environment a topic of constant discussion these days. Many environmental concerns were treated by early American nature writers, who recognized the beauty of the natural world in an age of commercial expansion. Some of the most famous writers of the 18th and 19th centuries wrote about nature, and their works are stylistic masterpieces. At a time when students are being encouraged to read and write about nonfiction, these masterworks of early American nature writing are all the more important. This book gives students and general readers a welcome introduction to early American nature writers.
Love Canal. Exxon Valdez. Times Beach. Sacramento River Spill. Amoco Cadiz. Seveso. Every area of the world has been affected by improper waste disposal and chemical spills. Common hazardous waste sites include abandoned warehouses, manufacturing facilities, processing plants, and landfills. These sites poison the land and contaminate groundwater and drinking water. A sequel to the bestselling Ecological Risk Assessment, Ecological Risk Assessment for Contaminated Sites focuses on how to perform ecological risk assessments for Superfund sites and locations contaminated by improper disposal of wastes, or chemical spills. It integrates the authors' extensive experience in assessing ecological risks at U.S. government sites with techniques and examples from assessments performed by others. Conducting an ecological risk assessment on a contaminated site provides the information needed to make decisions concerning site remediation. The first rule of good risk assessment is "don't do anything stupid". With the practical preparation you get from Ecological Risk Assessment for Contaminated Sites you won't.
Describes the past, development, settlement, and present culture of the African Congo, and profiles the adventurers who ventured into the unexplored land.
Conserving Words looks at five authors of seminal works of nature writing who also founded or revitalized important environmental organizations: Theodore Roosevelt and the Boone and Crockett Club, Mabel Osgood Wright and the National Audubon Society, John Muir and the Sierra Club, Aldo Leopold and the Wilderness Society, and Edward Abbey and Earth First! These writers used powerfully evocative and galvanizing metaphors for nature, metaphors that Daniel J. Philippon calls “conserving” words: frontier (Roosevelt), garden (Wright), park (Muir), wilderness (Leopold), and utopia (Abbey). Integrating literature, history, biography, and philosophy, this ambitious study explores how “conserving” words enabled narratives to convey environmental values as they explained how human beings should interact with the nonhuman world.
