The creation of these bird maps would not have been possible without the help of countless individuals and organizations. First and foremost, the hundreds of volunteers who have patiently submitted almost 100,000 data points during the past nine years sh ould get recognition for their contribution in creating the Breeding Bird Atlas (BBA) database. The Seattle Audubon Society is recognized for getting the BBA project started with financial and logistical support, and for continuing support. Cooperation was a key factor in this project's completion, with support coming also from many local Audubon societies throughout the state, and the Washington Ornithological Society. Fred Dobler and the Washington Department of Fish and Wildlife provided a key database for presence of shrub-steppe nesting birds, and their Natural Heritage Database, providing a key data source for preparation of maps for threatened/endangered species. Review of the maps was a crucial part of their creation, and we wish to sincerely thank the competent individuals who took the time to meticulously review and critique each and every map: Gene Hunn, Dennis Paulson, Alan Richards, Russell Rogers, Fred Sharpe, Andy Stepniewski, Bill Tweit, and Terry Wahl. Additional thanks are extended to David Manuwal, Kelly McAllister, Dennis Paulson, Russell Rogers, Andy Stepniewski, and everyone on the e-mail group 'Tweeters' for patiently answering questions regarding the distribution of species for which data were scarce. Some data was also supplied by The Nature Conservancy. Appreciation also should be expressed to Anne Avery, Judith Cress, and Gregory Stought for capable technical support of Sun Microsystems computers, advice regarding the Ingres database software, and GIS support whenever it was needed. Financial support for this project was provided by the National Biological Service through the Washington Cooperative Fish and Wildlife Research Unit at the University of Washington, Seattle.
