Remarks.—There is a considerable difference in color between 
the summer and winter plumages of the spruce grouse. The 
Labrador specimens are all in worn breeding plumage, and must 
therefore be compared, only, with examples of the more southern 
race in corresponding plumage. The female of the Labrador 
form can always be told at once from the female of true C. cana- 
densis, from Maine, by the greatly reduced amount of buffy or 
ochraceous, and the increased amount of gray and white, in the 
general plumage. ‘lhe male cannot so certainly be distinguished, 
although there are differences that show in series.
