Book Description
The ten currently recognized species of grouse in North America have played an important role in America's history, from the famous but ill-fated heath hen, a primary source of meat for the earliest New England immigrants, to the ruffed grouse, currently one of the most abundant and soughtafter upland game birds in more than 40 states and provinces. This book summarizes the ecology, reproductive biology, and social behavior of all ten of the extant North American grouse species. It also describes the current status of grouse populations, some of which are perilously close to extinction. The social behavior of grouse is of special biological interest because among these ten species there is a complete mating system spectrum, from seasonally monogamous pair-bonding to highly promiscuous mating patterns. The latter group illustrates the strong structural and behavioral effects of sexual selection resulting from nonmonogamous mating. These influences reach a peak in the development by some grouse species of engaging in mating "leks," arena-like competitions performed by males while attempting to attract fertile females, and also provide opportunities for females to select optimum mating partners. These sexual competitions also promote strong differences evolving in sexual signaling behaviors ("displays") among closely related species. Nevertheless, a relatively high incidence of mating errors and resulting hybridization often occurs in spite of these marked behavioral differences. In addition to a text of 101,000 words, the book includes 16 range maps, 37 line drawings, and 38 photographs by the author, as well as nearly 1,400 literature citations.

Book Description
A flock of Pinyon Jays arrive in a flash of blue, and leave again just as suddenly. This once mysterious bird is now the subject of over 20 years of intensive research involving over one thousand colour-marked jays by Russell Balda, John Marzluff and their colleagues and helpers. This plain blue bird has turned out to be anything but plain in its biology and behaviour. Uniquely dependent on the seeds of the Pinyon Pine for food, they have developed a number of behavioural and morphological adaptations to best utilise this resource, above all caching enough seeds each autumn to supply their needs throughout the winter and fuel their unusual habit of nesting in late winter. Fluctuations in pine-seed supply, both by season and between years, poses special problems for these birds and has led to their extremely flexible and complex social system in which learning and memory play an unusually large part. They store pine seeds and retrieve them with uncanny accuracy; they form lifelong pair bonds and nest colonially, occasionally involving younger birds to help established pairs rear the young; and they use their large vocabulary to coordinate activities within one of the largest known avian societies. This intriguing story will fascinate both the enthusiastic amateur birder and the professional alike. Packed with information, it presents Pinyon Jay biology in a readable form and places them into the wider context of studies on bird ecology and evolution. Fine illustrations by Tony Angell, with additional pictures by Caroline Bauder, complete this attractive addition to any birder's bookshelf.

Book Description
Mike Hudak traveled throughout the West speaking with former employees of wildlife and land management agencies, and citizens who have long advocated for better management of our public lands. Western Turf Wars is a compliation of these accounts - testimonies that reveal how and why the management agencies have failed to protect our public lands. Underlying that management failure is the cowboy myth's social and political legacies.

Book Description
Mary Zeiss Stange's story of running a bison ranch with her husband in southeastern Montana--on the outskirts of nowhere and far-from-here--is a narrative of survival in a landscape and a society at once harsh and alluring. In this series of essays she illustrates the realities of ranch life at a time when the "New West" of subdivision, "ranchettes," telecommuting, and tourism collides with the "True West" of too much, too little, too hard, and too harsh. This society is molded by the climate, and both run to extremes, simultaneously unforgiving, often brutal, yet capable of unalloyed charm and breathtaking beauty. Her stories explore the myths and realities of ranch life in modern America--the brandings, rodeos, and demolition derbies that are major events, and the social, environmental, and political factors at work in shaping the land and the people. Less memoir than deep history of people and place, these vivid, naturalistic tales examine the complex relationships that comprise life in the rural West today.

Book Description
The Sustainability in Prisons Project is a partnership between The Evergreen State College and the Washington State Department of Corrections. Our mission is to bring science and nature into prisons. We conduct ecological research and conserve biodiversity by forging collaborations with scientists, inmates, prison staff, students, and community partners. Equally important, we help reduce the environmental, economic, and human costs of prisons by inspiring and informing sustainable practices.
