Bighorn Sheep Info

Here's some interesting information about Bighorn Sheep (these seem to be a likely candidate for the rams in the story):

And here is a brief NatGeo video about rams and their head-bashery. Fair warning: there is a little bit of animals doing what animals do best near the end of the video:

First thing I noticed: the males have the iconic large curved horns, which are used for competitions with other males. The ewes themselves have smaller, less curved horns. But it's clear which horns look cooler.

Bighorn sheep live in alpine slopes and meadows, and travel around rocky slopes that they use to escape predators. The lambs live with their mother until they are 2-4 years old. If they are male, then they will join a group of bachelors. Females usually stay in their mother's group.

When rams get ready to headbutt, they run forward and lean back on their hind legs at the end, so they can come down on their opponent's head harder. Here is a (low-quality) video of a ram almost hitting a car a few times. Spoiler alert: he never actually does hit the car really hard, but he does demonstrate the movement I was talking about.

And finally, one image of a baby lamb.

They sure look flimsy and frail, which I guess is why they look adorable. I would want to protect this little guy, because I mean, just look at him!
