140 AMERICAN GAME BIRD SHOOTING 
Utah and western South Dakota to Alaska, along the 
Yukon and Mackenzie rivers, throughout much of Brit- 
ish North America, east as far as Manitoba. Another 
darker race (Bonasa umbellus sabint) inhabits the 
wooded country of the northwest coast region of south- 
ern Alaska, to Humboldt County, California. 
RUFFED GROUSE 
All these forms are very similar in appearance, and 
it is not unusual to find in one locality a bird which, in 
color, may closely resemble those of some far distant 
locality. The most that can be said for these races is 
that they average lighter or darker—as the case may 
be—than certain other relations, the center of whose 
abundance may be far distant.
