Redhead

americana
Primarily eastern Washington species, breeding in wetlands, lakes, ponds, and slow-moving streams east and north of Columbia River. Predicted to breed along whole length of Columbia River in Kittitas County by Washington Gap report (Smith et al. 1997). Pairs recorded twice in adjacent blocks along Columbia on 23–24 May 1997 support Gap prediction, although breeding habitat limited and local. Not recorded west of Cascades in our study except at Kent Ponds in southern King County, where breeding confirmed in 1988 and 1995.
