Male bighorn sheep are called rams. They stand about 3 feet tall and are 5 to 6 feet long. They weigh about 200 to 300 pounds. Females are called ewes. Ewes are smaller than rams.
Bighorn sheep have excellent eyesight.
Their fur is gray, brown, or tan. Their underbelly, rear end, and eye patches are light colored. In the summer, they shed the top level of their fur. Their horns are brown color and grow throughout their life. As rams grow old, their horns curl.
