The Atlas of Wintering North American Birds represents the effects of thousands of people who have participated in the Christmas Bird Counts, an annual event sponsored since 1900 by the National Audubon Society. Unlike a conventional field guide, the Atlas doesn't show what birds look like, but rather tells where to find them in the winter months. Terry Root has used the data from the 1963-72 counts to provide the first large-scale biogeographical account of birds wintering in North America. Using sophisticated computer techniques, Root has translated the data into both traditional contour maps and innovative new maps that stimulate three dimensions. The maps show at a glance that, for example, the Baltimore Oriole winters primarily along the eastern seaboard, with the densest populations in Florida between Tallahassee and Gainesville and in North Carolina from Rocky Mount to the Croatan National Forest.

Beautifully illustrated with color photographs, maps, graphs, and tables, the Oklahoma Winter Bird Atlas offers ornithologists and amateur birders alike a wealth of easy-to-read information about the status of bird species in Oklahoma. A companion to the Oklahoma Breeding Bird Atlas, this landmark volume by biologist Dan L. Reinking provides a detailed portrait of more than 250 species, from the oft-spotted Red-tailed Hawk, Dark-eyed Junco, and Northern Flicker to the rarely seen Blue-headed Vireo, Cassin’s Finch, and Verdin. The atlas—one of the first of its kind for winter birds—uses a combination of species accounts, grouped by scientific order, and illustrations to provide a systematic inventory of winter bird distribution across Oklahoma’s counties. Each species account includes a photograph of the featured bird in winter plumage, along with a brief description outlining the times of year it appears in the state, its habitat, its distribution across the state’s counties, and its behavior. Maps indicate surveyed locations in which the species was spotted, while charts and tables further describe the bird's abundance. The data compiled in this volume represent the work of more than 75 volunteers who conducted bird counts in both early and late winter for the George M. Sutton Avian Research Center. The data span five winters, 2003 to 2008, and 577 blocks of land. Comprehensively researched and thoughtfully presented, the Oklahoma Winter Bird Atlas will prove an invaluable resource for evaluating trends in bird populations that change over time due to such factors as urban expansion, rural development, and climate change.

The North American Breeding Bird Survey comprises a network of regularly censussed, road-based survey routes and constitutes the most comprehensive set of data on the relative abundance and population trends of these birds during the summer months. Its value was highlighted in 1989, when the data were used to confirm suspected population declines in a number of species of neotropical migrants breeding in the northeastern United States and Canada. In this book Jeff and Amy Price and Sam Droege have used these data to create detailed, computer-generated maps showing the relative abundance of 450 species that summer in the contiguous United States and southern Canada. Tabular information on distribution hotspots for these, and a further 50 or so species too local in occurrence to map effectively, are also presented. As a data-based survey, the focus of the maps is on places where occurrence has been systematically confirmed over a number of years. As such, the maps provide a baseline for future and more regionally based studies. Supporting chapters provide details on the survey methodology, the mapping procedures used, and some current concerns in North American bird conservation.

"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.

This companion volume to The Atlas of Breeding Birds of Britain and Ireland is derived from surveys of birds present in Britain and Ireland during the three winters, 1981/82, 1982/83 and 1983/84. The surveys were organised by the British Trust for Ornithology and the Irish Wildbird Conservancy, as were the earlier breeding birds surveys. The Winter Atlas maps 200 species, 192 of which have full-page two-colour maps faced by a page of text. The texts (written by over 100 specialists) comment on the survey results, the species generally and the distribution and abundance as mapped. In addition there are introductory chapters on the maps, the weather in the three winters, bird patterns and movements; and appendices describing the planning, organisation, field methods, and processing of the survey data from record cards to computer output and maps. A team of 23 artists, led by Robert Gillmor, has provided the line drawings which head the species accounts.

Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.
