Rocky Mountain Elk (Cervus elaphus nelsoni) harem bull in full rut. To be dominant,a bull must be big,strong,and in his prime,from 5 to 12 years old. A bull's antlers tell much of his story. Bulls in their prime have the largest,most magnificent antlers. Other male and female elk measure the physical worth,and to a certain extent,the behavioral worth,of a bull by looking at his antlers.
