Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Paul Johnsgard, one of the world's leading ornithologists, has written this book as a call to action. Conservationists have seen a marked decline in the populations of North American grouse, particularly the grassland-adapted species. Unless action is taken swiftly, at least one species -- Attwater's prairie-chicken -- is certain to follow the heath hen into extinction. Johnsgard begins with the tragic history of the heath hen, which became extinct in 1932. He devotes a chapter each to the greater and lesser prairie-chickens, greater and Gunnison sage-grouse, and sharp-tailed grouse. Johnsgard argues that habitat loss and excessive hunting are major factors contributing to the decline of each species, particularly the lesser prairie-chicken and the Gunnison sage-grouse, which have been proposed for threatened federal status. This narrative history is troubling but not without hope. Johnsgard discusses places where populations exist that have yet to be preserved, and outlines the steps necessary to conserve these species. A possible future does exist for grassland grouse, and Johnsgard's book points the way toward securing it.

This book was released on 1992 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selection of nesting habitat in relation to vegetation heterogeneity and spatial scale of analysis was studied for plains sharp-tailed grouse (Tympanuchus phasianellus jamesi) in the Nebraska Sandhills to test the nesting component of a Habitat Suitability Index model. I tested the validity of estimating nesting suitability from mean effective height (MEH) (height to which a graduated pole is completely obstructed) of dried herbage in early spring, without regard to spatial heterogeneity in MEH. New Local Variance (NLV), a blocked-quadrat method for estimating mean patch size, was more effective than Two-Term Local Quadrat Variance and coefficient of variation for quantifying vegetation heterogeneity. Smoothing transect data with a compound data smoother prior to NLV analyses facilitated interpretation of results and clarified MEH patchiness in plots of the data. MEH pattern was apparently influenced by topography, snow compaction, rodent burrowing,and grazing and trampling by cattle.
