Colorado Chipmunk 
173 
Habits. — This species is an inhabitant of the cedar and 
pinon zone, as observed in Routt County, extending a httle 
up into the yellow pines, its range of altitude being from 
6,000 to 7,000 feet. It seemed to prefer rocky ground, and 
was wild and shy in its behavior, rendering it difficult to 
obtain specimens by shooting. 
It is easily distinguished from any other of our Colorado 
Chipmunks by its peculiar coloration, entirely different 
from that of the rest.
