How to Identify Bighorn Sheep in Idaho
Yes, you can identify bighorn sheep in Idaho by their large, curved horns and muscular, brown bodies. Idaho is home to two distinct types of bighorn sheep, each adapted to different rugged environments. To identify them, look for their white rump patches and the massive, spiraling horns found on the males. These agile climbers are often seen on steep, rocky cliffs in areas like the Salmon River canyons and the Sawtooth Valley where they can easily evade predators.

How to tell a bighorn sheep from its lookalikes in Idaho
Only one species of bighorn sheep lives in Idaho, so the real question is telling it apart from its relatives. 2 other members of the sheep, goat and cattle family have a verified observation record here, each with at least 10 confirmed sightings. The ones you are most likely to confuse it with are Mountain Goat and Domestic Cattle. Compare them below, ranked by how often each is recorded.

Yes, you can identify bighorn sheep in Idaho by their large, curved horns and muscular, brown bodies. Idaho is home to two distinct types of bighorn sheep, each adapted to different rugged environments.

What does a bighorn sheep look like?
A bighorn sheep has a thick, sturdy build with a coat that ranges from light brown to a deeper chocolate color. They are easily identified by their prominent white rump patch and the white markings on the back of their legs. Males, or rams, have massive horns that can weigh up to 30 pounds, while females, or ewes, have much smaller, slightly curved horns.
How to identify bighorn sheep horns?
Rams have thick, curled horns that continue to grow throughout their lives, often forming a full circle as they age. Ewes have shorter, more slender horns that resemble those of a domestic goat. The horns are permanent and are not shed each year, unlike the antlers of deer or elk found in the same Idaho habitats.
What are the signs of bighorn sheep in Idaho?
Look for tracks that are heart-shaped and similar in size to a deer's but with straighter edges. You may also find 'beds' on steep slopes where the sheep have cleared away rocks to rest. In the Salmon River country, you might hear the loud, echoing crack of rams clashing horns during the fall rut, which is a definitive sign of their presence.
How to tell a bighorn sheep from a mountain goat?
While both live in rocky terrain, bighorn sheep have brown coats, whereas mountain goats are pure white. Bighorn sheep also have thick, curved horns, while mountain goats have short, sharp, black horns. Bighorn sheep are generally more muscular and lack the long, shaggy 'beard' and leg pantaloons that mountain goats possess.
What does a bighorn sheep look like when moving?
Bighorn sheep move with incredible confidence on nearly vertical surfaces. They have a powerful, jumping gait and use their specialized hooves to grip the smallest rocky ledges. When running on level ground, they have a steady, rhythmic trot, but they almost always head for the safety of the cliffs if they feel threatened.
Can you identify bighorn sheep by their calls?
Bighorn sheep are generally quiet, but they do make occasional bleats similar to domestic sheep. During the rut, rams may let out loud grunts. However, the most recognizable sound associated with them is the thunderous impact of their horns during combat, which can be heard from over a mile away in the deep canyons of Idaho.
