Canace obscura var. fuligniosa
[sic] Ridgway, 1873,
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.
