About this project in BBA Explorer
Kelly Cassidy of Washington kindly sent us a copy of the atlas dataset as a GIS shapefile and an attached table in July, 2004. Data are presented here by agreement between the atlas project, NBII, and USGS Patuxent Wildlife Research Center.
Results should be cited as:
Breeding Bird Atlas Explorer (online resource). 2018. U.S. Geological Survey Patuxent Wildlife Research Center. <Date of access>. Data extracted from: Smith, M.R., P.W. Mattocks, Jr., and K.M. Cassidy. 1997. Breeding Birds of Washington State. Volume 4 in Washington State Gap Analysis- Final Report (K. M. Cassidy, C.E. Grue, M.R. Smith, and K.M. Dvornich, eds.). Seattle Audubon Society Publications in Zoology No. 1, Seattle, 538 pp.
Use Policy
Data from this project are available for use but must be accompanied by the line "Used by the permission of the Seattle Audubon Society." For questions or to use large portions of the dataset, please contact the Seattle Audubon Society at
This project was coordinated by the Seattle Audubon Society with assistance by members of the Washington Gap Analysis Project. The Washington Ornithological Society and numerous local Audubon chapters and state agencies also provided support.
Treatment of the received dataset

We imported the received dataset with modifications as follows to better combine with other atlases or to match publication cited above:

  • Included the following species that were not mapped in the published atlas but were reported with data of PO or higher:
    • Brandt's Cormoran, Trumpeter Swan, American Black Duck, Arctic Tern, Ancient Murrelet, Acorn Woodpecker, Sky Lark, Northern Mockingbird, Bohemian Waxwing, and Golden-crowned Sparrow.
  • Grouped the American Crow and Northwestern Crow as unid. Crow because they were mapped together in the published atlas.
  • Mapped the following species only at township-range level to match the published atlas:
    • Northern Goshawk, Golden Eagle, Ferruginous Hawk, Prairie Falcon, Peregrine Falcon, and Spottel Owl.
