First published in 1952 The Sage Grouse in Wyoming was a seminal work, the first comprehensive study of the several species of western grouse. The author, Robert L. Patterson led the study from 1948 - 1952. This comprehensive treatise includes the first complete study of the natural history of the sage grouse, initially described by Lewis and Clark in 1806. The book is divided into three parts. Part I presents an overall view of the physical and biotic environment, diseases, parasites and other factors influencing population density. Part II is devoted to natural history and Part III is devoted to the influence of man's activities on population density.

The North American Grouse: Their Biology and Behavior

Author: Paul Johnsgard

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. The book includes 16 range maps, 37 line drawings, and 38 photographs by the author, as well as nearly 1,400 literature citations.

Falconer on the Edge

Rachel Dickinson profiles falconer Steve Chindgren, a man willing to make extreme sacrifices to continue practicing the sport that has ruled his life. Dickinson arrives at a sense of falconry’s allure: the unpredictable nature of the hunt and the soaring exhilaration of success. Further exploration unveils the enormous emotional cost to a falconer who establishes an extraordinary tie to his birds. When, in the space of two days, Chindgren loses two birds that he’d been training for years, he is plunged into a profound depression that is only deepened when Jomo, his best bird, slows down because of old age. In addition to this challenge, Chindgren faces the danger to falconry that the modern world presents. Grouse habitat is being degraded by mining, agriculture, and gas industry interests. And the number of falconers is dwindling—the corps is graying and has few acolytes. Falconry is a sport that requires persistence, stoicism, and sacrifice; in this captivating account, Dickinson illuminates a fascinating subculture and one of its most hardcore personalities.

Travels in the Greater Yellowstone

Award-winning nature writer Jack Turner directs his attention to one of America's greatest natural treasures: the Greater Yellowstone Ecosystem. Comprised of two national parks, three national wildlife refuges, parts of six national forests, and eleven wilderness areas, Greater Yellowstone is a vast array of differing environments and geographies. In a series of essays, Turner explores this wonderland, venturing on twelve separate trips in all seasons using various modes of travel: hiking, climbing, skiing, canoeing lakes, floating rivers, and driving his way across the landscape. He treks down the Teton Range, picks up the Oregon Trail in the Red Desert, and floats the South Fork of the Snake River. Along the way he encounters a variety of wildlife: moose, elk, trout, and wolves. From the treacherous mountains in the dead of winter, to lush river valleys in the height of fishing season, his words and steps trace one of the most American of experiences---exploring the West. Turner, who has lived in Grand Teton for three decades, designates Greater Yellowstone as ground zero for the country's conflict between preservation and development. At a time when the battle to preserve a wild and natural environment is relentless, his accounts of the areas conflicts with alien species, logging, real estate, oil, and gas development are alarming. A mixture of adventure, nostalgia, and Americana, Turner's rare experiences and evocative writing transform the sights and sounds of Greater Yellowstone into an intimate narrative of travel through America's most beloved lands. Praise for Teewinot: "Bursting with a sense of place...a rewarding reading experience replete with ravishing observations of nature." - Publishers Weekly "...a measured luxuriance in the landscape, a love song to the natural history of a place...Turner's writing is muscular, never swaggering, and almost lyrical, summoning a Teton Range in its rightful, sublime austerity." - Kirkus Reviews "Teewinot is a rare book. The wonderful accounts of mountaineering serve as armature not only for Turner's meditative reverence for the Grand Tetons and his often evocative prose but also for an uncommon density of knowledge of place..." - Peter Matthiessen, author of Tigers in the Snow "This is, simply stated, a wonderful and utterly engaging book." - Jim Harrison, author of Dalva and The Road Home "Each place must find its muse. The Tetons have found theirs and his name is Jack Turner." - Terry Tempest Williams, author of Coyote's Canyon
