Taxonomic Comments
Troglodytes pacificus was formerly included in T. troglodytes (Linnaeus 1758) [Eurasian Wren], but here considered specifically distinct on the basis of differences in vocalizations (Kroodsma 1980, Hejl et al. 2002) and mitochondrial DNA (Drovetski et al. 2004) (AOU 2010).

Range Extent Comments
Breeds from the Alaska Pacific coast (from the Aleutians east, including the Pribilof Islands) and coastal and central British Columbia (including Queen Charlotte and Vancouver islands) south to central California (San Luis Obispo County, and the western slope of the central Sierra Nevada), northeastern Oregon, central Idaho, northern Utah, western Montana, and southwestern Alberta. Reports of singing birds in northern Arizona, northern New Mexico, and the Rocky Mountains of Colorado are presumed to refer to this species, but confirmation is required.

Winters in breeding area and south to southern California, southern Arizona, and southern New Mexico (rare). Sight reports from Sonora probably represent pacificus rather than hiemalis, but confirmation is required.

Accidental in northern Alaska (Point Barrow).
