Hermit Warbler Dendroica occidentalis

Core Washington breeding range lies west and south of our four-county area, with closest approach across Hood Canal on east flanks of Olympics. Regularly hybridizes with Townsend's Warbler where breeding ranges meet. Scattered "possible" records from King and southern Kittitas Counties represent spring overshoots or remnant breeders whose parental pedigree may be suspect, due to difficulty of identifying some hybrid forms. BBA teams did record many certain hybrids (not mapped). Some Kitsap County records near Green Mountain from first atlas phase may represent "pure" Hermit Warblers, although systematic searches during second phase and beyond have turned up only hybrids.
