Named after their curved horns, the Bighorn sheep is a species of sheep native to North America. There's a very good chance you'll see these animals when you visit Big Sky, Montana.

Bighorn sheep live in the town of Big Sky and the surrounding mountains of Southwest Montana. If you're lucky you'll spot a herd near the entrance to Big Sky on Highway 64 licking salt near the side of the road, along Highway 191 near the banks of the Gallatin River, or deep in the mountains while on an epic Big Sky wilderness hike. These beautiful creatures are fun to spot, but always give them the respect that they deserve.

  • Their two-toed split hooves help with grip and balance.
  • They range from southern Canada through the western US and down into Mexico.

  • Bighorns typically swallow their food and then regurgitate it later and chew it up more before swallowing it!
  • In November, during the rut season, or mating season, bighorn rams will compete by butting heads. They race at 20 MPH and crack their foreheads against each other. The sound travels up to a mile away.
  • Butting heads is done for mating rights or for dominance.
  • Bighorn lambs are typically born in spring from April to June.
  • Gray-brown coats help them blend in to the mountainside.
  • Bighorn sheep are social animals that live in herds, or bands, of 5 to 15. Ewes and lambs typically live together and rams typically live separately in groups of 2 to 5.

Bighorn sheep are wild animals. There are a few cases of bighorn sheep attacking humans, but it's rare. They are typically not aggressive animals, but can get defensive - especially during rutting season. You wouldn't want them to use their horns to butt you! Always give them plenty of space.
