For most of the year, adult bighorn rams and ewes live separately. This is obviously not conducive to species propagation, so in the fall, they come together and the wooing begins.
Rams gather and jostle one another probably as a way to establish dominance.
When jostling does not settle dominance, head butting does.
Ewes show scant courtship towards rams. Their contribution seems primarily that of turning up. Here they are pouring down to the valley floor from the cliffs. Let the wooing begin.
Six rams follow one ewe.
A ram must determine the state of a ewe’s oestrus and this might involve licking her flanks and gently stroking her rump with his foreleg.
This ram obviously hopes the ewe is ready.
Five rams tagging along behind one ewe have probably smelled her pheromones.
A ram in hot pursuit has already smelled pheromones and has now opened his mouth to expose another organ which aids in determining if the ewe is in oestrus.
A young ram tries unsuccessfully to mate. 
Great series of photos. Hopefully the wooing will produce many more sheep.
Lorna, the saga continues tomorrow.
Well I think you got the full story you were imagining.
Nicely done!
Travis, and what I managed to get is thanks to you. I would never have found those great observing locations without your help.
