The Bighorn Sheep herd from Yellowstone National Park that we saw on Old Yellowstone Road has at least nine mature rams. This little band of three rams was together every time we saw the herd. Each of them has a distinctively different set of horns from tightly curled like the ram looking up to flared out or more loosely swept. The more tightly curled the horns, the less likely that brooming will be visible on the tips. Brooming is the wearing down of the horns from rubbing on rocks and the ground or clashes with other rams. The tight curled horns of the ram on the right seem to have kept the tips in good condition.
