Adult rams live in bands that seldom associate with ewe groups except during the mating season, or rut, in late November and early December. The head butting that rams are known for is the way males establish their reproductive rank.

Females (known as ewes) also carry horns, but theirs are shorter and more slender, and only slightly curved. Until rams reach the age of 3 years, they tend to resemble the ewes quite a bit. After that, continued horn growth makes the males easily recognizable. Horns grow steadily during spring, summer, and early fall. In late fall or winter, horn growth slows and eventually ceases. This start-and-stop growth results in a pattern of rings called annuli which are spaced along the length of the horn, and can help determine age.
