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.

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.

A personal, lively, in-depth account of the life and lore of the roadrunner.

Examines over 270 species of birds known to breed in Arizona, complete with color photos and nesting and migratory data.

It is of practical interest to know the amount of data required to produce reliable models. I developed nine training sets of from 50 to 450 sites for each species to predict occurrence in a 100-site test set. Model performance was determined by the reduction in error of prediction (tau-p) compared to the null. On average, model performance leveled off after 300 sites.

This beautifully illustrated study is the first book to focus on the birds of prey of New Mexico.
