Sample Atlas Maps: The following maps and layout are a sample of what the Breeding Bird Atlas CD contains. We start with a species overview. (All maps and text are copyright © 2001 by Oregon Field Ornithologists, all right reserved.)

White-headed Woodpecker Picoides albolarvatus Synopsis: Nests in cavities of large ponderosa pine mainly east of the Cascade crest, as well as locally in the Siskiyou Mountains. Most notable are the records from northern Harney County. Habitat Associations: strongest Ponderosa Pine-dominant Mixed Conifer Forest (367449 acres) Ponderosa Pine Forest/Woodland (3534556 acres) Ponderosa-Lodgepole Pine on Pumice (1192347 acres) strong Northeast Mixed Conifer Forest (2405711 acres) Ponderosa Pine-W. Juniper Woodland (116251 acres) Grassland & Fir-Ponderosa Interspersed (306329 acres) lesser Subalpine Fir-Lodgepole Pine Montane Conifer (380656 acres) True Fir-Hemlock Montane Forest (974450 acres) Relative Detectability: Somewhat difficult to detect and to confirm nesting. This species has been the focus of survey efforts on some government lands, and those data have been included. Challenge: Determine if it currently nests in mountains of Curry, Josephine, western Jackson, or southeastern Lake Counties. Determine if it is present more widely in northern Wheeler County and Blue Mountains of southern Umatilla, southern Union, and southern Baker Counties.

Clicking on the thumbnail of the distribution map in the above overview brings up a larger map that shows the hexagons, colored for "possible," probable," and "confirmed."

Clicking on the thumbnail of the habitat map in the above overview brings up a larger map that shows suitable habitat overlaid with the actual sightings.

Clicking on any of the hexagons within this habitat map brings a closer view of the habitats and breeding levels.

Then, clicking on any of the hexagons within this map brings a close-up map of the hexagon and a link to the details of all the bird sightings recorded for that hexagon.

This is only a sample of what's on the Atlas CD. All the data for the squares is included. There are distribution maps and photographs of all the habitats within the state. There is data on which hexagons recorded the most species, and which hexagons received the most birding coverage. There are lists of what species that were expected in each hexagon weren't found. In addition, there is the Atlas purpose, procedures, and background information, along with help screens to explain all the maps and data.
