A small group or mob of bachelor Bighorn sheep (Ovis canadensis), shedding their heavy winter coats in early Spring, roam the grasslands of Badlands National Park. After their first year with their mothers, dominance relationships become evident. These behavioral interactions are closely tied to dominance rank. Direct reproductive benefits of high rank, in terms of more breeding opportunities, are obvious and the individuals become serious in their efforts to display their dominance.
