The Canada Grouse 153 



Richardson's grouse 



(Z?. 0. richardsoni) 



The chief difference between this race and Z>. 

 obscurus is found in the tail, which in Richardson's 

 grouse is square at the tip and lacking the con- 

 spicuous gray band. It, too, is a mountain dweller, 

 being found along the eastern slopes of the Rockies 

 from central Montana northward through the moun- 

 tain region of Canada, and has no peculiarities of 

 habits to distinguish it from its near relatives.
