Great Plains Birds
Author: Larkin PowellPublisher: U of Nebraska Press
ISBN: 1496218590
Category : Nature
Languages : en
Pages : 162
Book Description
2020 Nebraska Book Award The Great Plains is a well-known and well-studied hybrid zone for many animals, most notably birds. In Great Plains Birds Larkin Powell explores the history, geography, and geology of the plains and the birds that inhabit it. From the sandhill crane to ducks and small shorebirds, he explains migration patterns and shows how human settlements have affected the movements of birds. Powell uses historical maps and images to show how wetlands have disappeared, how grasslands have been uprooted, how rivers have been modified by dams, and how the distribution of forests has changed, all the while illustrating why grassland birds are the most threatened group of birds in North America. Powell also discusses conservation attempts and how sporting organizations have raised money to create wetland and grassland habitats for both game and nongame species. Great Plains Birds tells the story of the birds of the plains, discussing where those birds can be found and the impact humans have had on them.

Global Warming and Population Responses among Great Plains Birds

Pages : 386
Book Description
"Based on an analysis of 47 years (1967-2014) of Audubon Christmas Bird Counts (CBC), evidence for population changes and shifts in early winter (late December) ranges of nearly 150 species of birds in the Great Plains states is summarized, a region defined as including the Dakotas, Nebraska, Kansas, Oklahoma, and the Texas panhandle. The rationale for this study had its origins in Terry Root's 1988 Atlas of North American Wintering Birds. ... The present analysis includes all of the 40 annual CBC surveys from the 1967-8 to the 2006-7 counts, plus the results of the most recent 2013-14 CBC. The present summary quantitatively describes the early winter abundance for 147 of the most commonly encountered regional species, illustrating their temporal changes in geographic distributions and relative abundance between 1967 and 2014"--Publisher description.

Wings over the Great Plains: Bird Migrations in the Central Flyway
Author: Paul JohnsgardPublisher: Lulu.com
ISBN: 1609620283
Category : Science
Languages : en
Pages : 248
Book Description
"The Central Flyway has been recognized as a collective North-South migratory pathway centered on the North American Great Plains for nearly a century, but it has never been analyzed as the species that most closely follow it, or the major stopping points used by those species on their journeys between their northern breeding and southern wintering grounds. A total of 114 U.S. and 21 Canadian localities of special importance to birds migrating within the Central Flyway are identified and described in detail. Judging from available regional, state and local information, nearly 400 species of 50 avian families regularly use the Central Flyway during their migrations. Nearly 90 Central Flyway species have wintering areas parly extending variably far into the Neotropic zoogeographic realm, and at least 50 of these winter entirely within the Neotropic realm. A few of these species undertake some of the longest known migrations of all birds, in excess of 8,000 miles in each direction. Seven maps, 49 figures and over 100 literature citations are included."--Abstract.

Book Description
"Johnsgard provides an overview of the history, current status, and uncertain future of prairie birds, from falcons and shorebirds to larks and sparrows. Some are intercontinental migrants that winter in South America, others sedentary species or short-distance travelers that may frequent the grasslands of Mexico. Johnsgard describes each species - its features, habits, habitats, migratory patterns, and breeding season ecology.".
