Stone sheep are named after the American hunter-explorer Andrew J. Stone. They are a subspecies of Dall sheep, and are sometimes referred to as “thinhorns” because their horns are smaller than the bighorn sheep found farther south.
Male Stone sheep have large, strongly curved horns , while the females have smaller, straighter horns. Their horns continue to grow throughout their lives – they don’t fall off like the horns of members of the deer family.
The size of a ram’s horns determines his status in a herd. Males use their horns for battering each other during mating season.
Stone sheep eat grass, wildflowers, and leaves of shrubs. They seek out salt deposits to lick wherever they can find them.
