Food consumption by the cliff chipmunk, Eutamias dorsalis, was observed in northern Utah in the natural habitat during May, June, July of 1965, 1966. Plant food sources nearest the cliff den sites were used in early spring, and as the season progressed, chipmunks increased ranges proportionately with the positioning of specific maturing food plants. Total daily frequencies of plant use suggested the following plants as prime energy sources in order of observed usage: Tragopogon, Balsamorhiza, Poa, Lomatium, Bromus, Crepis, Amelanchier, Agoseris.
