Use of Ancillary Bird Data
A small portion of the records in our database represent observations by persons who were not atlasing (and may not even have known about the atlas project), but were collecting data for other bird monitoring or research projects during the 1995-1999 breeding season. We made exhaustive efforts to identify all such contemporary projects, obtain permission for use of data, and convert the data to our grid and database formats. Consequently, our atlas database includes all 1995-1999 data from Breeding Bird Survey (BBS) routes [http://www.mp2-pwrc.usgs.gov/bbs/index.htm]; USDA Forest Service point counts (Huff et al. 1999); MAPS banding stations [http://www.birdpop.org/maps.htm]; surveys by BLM, USDA Forest Service, and the Oregon Natural Heritage Program of threatened/endangered and special-interest species (e.g., Spotted Owl, Marbled Murrelet, Snowy Plover); published field notes in Oregon Birds and American Birds; some private industry-sponsored point counts (e.g., Weyerhaeuser, Willamette Industries, Boise-Cascade, Idaho Power Company); some data from animal rehabilitation centers; and virtually all of the relevant university theses and research studies. Also, following the final field season, two project volunteers visited selected field offices of the USDA Forest Service and BLM and obtained additional information on a few species from wildlife specialists who had not participated in the project.
