Bird enthusiasts will find viewing loca-tions and updated contact information for hundreds of sites in Wy-oming, Colorado, Montana, Idaho, Alberta, and British Columbia. Part 1 outlines the habitats, ecology, and bird geography of the Rocky Mountains north of the New Mexico-Colorado border, including recent changes in the ecology and avifauna of the region. It provides detailed lists of major birding locations and guidance about where to search for specific Rocky Mountain birds. Part 2 considers all 328 regional species individually, with information on their status, habitats and ecology,...

This 100,000-word monograph summarizes the distribution, abundance and breeding biology of the 183 species of wetland-adapted birds reliably reported from South Dakota, Nebraska and Kansas through 2011. These include 91 species known to breed or have historically bred in the region, 51 species that migrate through the region but are not yet known to breed or have bred there, and 41 species that are extremely rare, probably extinct, or for which evidence as to their current occurrence is questionable. Brief summaries of the breeding biology of all the regionally nesting species are provided,...

The great North-South migratory pathway across the North American Great Plains-from the tropic wintering grounds to the high arctic breeding areas-is analyzed for the first time. Describes 114 U.S. and 21 Canadian localities of special importance to migrating birds. Discusses nearly 400 species of 50 avian families. Includes 7 maps, 49 figures and over 100 literature citations.

This book summarizes the evidence from 47 years (1967-2014) of Audubon Christmas Bird Counts and finds that bird populations and winter ranges have changed for many species in the Great Plains states (the Dakotas, Nebraska, Kansas, Oklahoma, and the Texas panhandle). The book offers quantitative descriptions of the winter abundance for 147 of the most commonly encountered regional species, illustrating their changes in geographic distributions and relative abundance between 1967 and 2014. As winters have become progressively warmer, the winter distributions of many birds have moved northward,...

These fourteen essays originally appeared in Prairie Fire, a monthly newspaper that for seven years has carried important messages of social, environmental, and economic issues to residents of Nebraska, Iowa, Colorado, and South Dakota, and subscribers in the rest of the world. They discuss the North American east-west ecological boundaries, spring migration events, bird feeders, feathered survivors of a glacial past, the threatened sharp-tailed grouse, the effects of climate change, some "sacred places"-Aransas National Wildlife Refuge, the Ashfall Fossil Beds, Squaw Creek Refuge, the Hutton...
