The writing of the species accounts of Sound to Sage
was essentially completed in the first three months of 2005. Consequently, no publications
or bird records later in date than 2004 were utilized or are cited here. Although
we were unable to consult them, we wish especially to call attention to two important
titles that appeared in the immediately following months:
- Swan, E. 2005. The Birds of Vashon Island: A Natural History
of Habitat and Population Transformation 1850–2005. Swan Company, Vashon,
- Wahl, T.R., B. Tweit, and S.G. Mlodinow (eds.). 2005. Birds
of Washington: Status and Distribution. Oregon State University Press, Corvallis.
