Their ranges in-clude the territory from the westernboundary to the highest peaks, but, withone exception, they do not overlap. The Tahoe chipmunk is found in theareas occupied by three other kinds. Thisis probably because it has a much greatertendency to take refuge in trees and huntfood in bushes. Consequently, it does notseriously compete with the others, whichare largely ground dwellers.
