In naming this subspecies, Dr. Miller (1933) gives the following comparison with the type race: “Size, and tone and hue of coloration as in P. c. canadensis of central British Columbia, but dark color of occiput not surrounding or even extending to orbit; entire pileum, anterior breast and throat white, the white of head above and below standing in sharper contrast to dark grays and black of occiput and body; collar purer white and broader.”

He designates its principal range as “in the relatively humid forest regions of northern Idaho, the principal trees of this forest being Engelmann spruce, western white pine, western larch and Douglas fir.”

The A. O. U. committee (1944) applied the above common name to this race and gave its range as “southern British Columbia to central Oregon and central Idaho.” A little farther south this race evidently intergrades with capitalis, and its habits are probably similar to those of this Rocky Mountain form.
