Ten years in the making, The Kentucky Breeding Bird Atlas presents the results of a seven-year survey of all birds that nest in the Bluegrass State, providing photographs of each species. This work summarizes the distribution and abundance of these bird species, and describes such recent phenomena as the invasions of the Blue Grosbeak and House Finch and the notable decline of other familiar species. Introductory material outlines the methodology used to complete the survey and summarizes its results. Of particular interest, this work helps to document the effect human alteration of the landscape has had on our bird populations. Some of the most common and widespread species in Kentucky today, for example, may have been among the most rare only two hundred years ago. Information for each species includes its current and historical status in the state, habitat preferences, specific details of the construction and placement of nests, and other pertinent aspects of nesting biology. Results of the survey are organized by physiographic region and degree of forestation. For rare or locally distributed species, more specific details concerning individual breeding records are given. Accompanying maps plot each species' distribution and abundance within the state. An additional section briefly summarizes the former status of twelve extinct or extirpated species. The Kentucky Breeding Bird Atlas is sponsored by the Kentucky State Nature Preserves Commission and the Nongame Wildlife Program of the Kentucky Department of Fish and Wildlife Resources in cooperation with the Kentucky Ornithological Society.
This Atlas is the first stage in the precise documentation which may aid
interpretation of distribution changes. As already noted (page 18), over 1,800
British records of rare or locally rare birds were submitted on secret cards. At the

Kenya, a country only the size of Texas, has one of the richest avifaunas in Africa. This atlas is an explanatory overview of Kenya's 1065 species, essential both to the birdwatcher as a means of finding birds and interpreting the significance of field observations, and to the ornithologist as a standard reference work.

"The Iowa Breeding Bird Atlas"—the first comprehensive statewide survey of Iowa's breeding birds—provides a detailed record of the composition and distribution of the avifauna of the Hawkeye State. The atlas documents the presence of 199 species, 158 of which were confirmed breeding. This landmark volume will alert Iowans to the limited distribution of numerous species and serve as a guide to the management practices—such as forest and wetland management, set-aside programs, reduction in farm chemical use, and crop diversity—which could help insure that many future changes are positive ones. "The Iowa Breeding Bird Atlas" provides a welcome and much-needed baseline for future comparisons of changes in Iowa's birdlife and, by extension, the lives of all animals in the state.

It is with thanks to the unstinting efforts of a small team of workers in Botswana (Africa), and to the meticulous keeping and analysis of records by the author, that ornithologists and conservationists have a work which will serve as a baseline of bird distribution. The Bird Atlas of Botswana summarizes the records collected. The information is introduced by an extensive and well-researched introductory set of chapters covering the ornithology, geology, botany, and geomorphology of Botswana. This sets the scene for the distribution maps which follow, showing not only the distribution in Botswana, but also seasonal abundance and movements there, as well as the distribution of each species throughout Africa.

In 1974, the Massachusetts Audubon Society and the Massachusetts Division of Fisheries and Wildlife launched a five-year survey to map the distribution of all the birds that breed in the Commonwealth - the first such comprehensive effort in North America. Nearly 600 volunteers spent countless hours in the field collecting data. This landmark volume presents the results of their efforts. The book includes distribution maps showing possible, probable, and confirmed breeding areas for 198 Massachusetts nesting species on a grid of 989 tensquare-mile blocks. Opposite each species map is a summary account giving historical perspective, relative abundance, habitat, seasonal schedule, nest, egg, and song descriptions, clutch size, egg dates, number of broods, and other pertinent details. Each species account is illustrated with a scrupulously accurate, watercolor portrait by award-winning nature artists John Sill and Barry Van Dusen. The book also includes a set of six transparent overlay maps in an attached pocket that allow the reader to correlate key environmental factors with the distribution of nesting species. Introductory sections describe the atlas survey methodology, and two appe

The Missouri Breeding Bird Atlas Project, conducted from 1986 through 1992, sought to document the status and distribution of the bird species that breed in Missouri. The primary goal was to develop a distributional map for each species that depicts as accurately as possible its true breeding range in the state. The resultant information was intended to: 1) provide baseline data against which future changes in the status and distribution of Missouri's breeding birds could be measured, 2) determine the location of rare species, 3) identify significant habitats and 4) develop a factual database to assist environmental planners in making wise decisions about resource use in Missouri. During the process of collecting the distributional and status information, data were also obtained on species' abundance, breeding phenology and Brown-headed Cowbird brood parasitism. --from Introduction (p. 1).

Birding is the fastest-growing outdoor pursuit in America. This landmark volume, Oklahoma’s first breeding bird atlas, offers both amateurs and ornithologists a wealth of information about Oklahoma bird species and their distributions. Lavishly illustrated with over 200 color photographs and 200 color maps, the Oklahoma Breeding Bird Atlas is as attractive as it is informative. During the years 1997-2001, more than 100 volunteer birders and professional researchers surveyed nearly 600 locations across all regions of Oklahoma. Their careful records form the basis of the maps in this volume, which show at a glance the breeding distribution of bird species both common and rare in Oklahoma. Detailed species accounts, illustrated with stunning photographs as well as maps, provide information on plumage, habitat, nesting habits, eggs, and the young. An invaluable reference for birders, ornithologists, and natural resource specialists, the atlas will be useful both today and in the future for understanding changes in bird populations over time. The Oklahoma Breeding Bird Atlas is the result of a cooperative effort between the Oklahoma Biological Survey and the Sutton Avian Research Center.
