Taxonomy:

Canace obscura var. fuligniosa

Cascade Mountains and Chiloweyuck Depot, Washington

.

Often lumped with D. obscurus, but separated#R on basis of molecular evidence#R, a decision supported by yellow, not red, exposed breast patch in display (3); distinct pale tailband (2); and differences in hooting song#R, involving usually six vs usually five syllables (“hoots”) given at both higher pitch (110–175 Hz vs 50–100 Hz) and louder volume (audible to 500 m vs audible to 40 m) (at least 2). Races sierrae and howardi sometimes placed in D. obscurus#R. Four subspecies recognized.

Subspecies and Distribution
  • D. f. sitkensis Swarth, 1921 – Alexander Archipelago (SE Alaska) S to Queen Charlotte Is (British Columbia).
  • D. f. fuliginosus (Ridgway, 1873) – coastal mountains from S Yukon and British Columbia (including Vancouver I) S to NW California, ranging interiorly in N California to W Siskiyou and Trinity Counties.
  • D. f. sierrae Chapman, 1904 – inner coastal ranges of W USA from C Washington (Cascades) S to C California (Sierra Nevada), E to Warner Mts and W Nevada (Carson Range).
