The Canada Grouse 153 



RICHARDSON'S GROUSE 



(Z?. o. richardsont) 



The chief difference between this race and D. 

 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.
