A. Rocky Mountain Bighorn Sheep are not an endangered species. Hunting is permitted and in Wyoming, approximately 200 permits are issued each year. It is very rare that the rams are killed in their dominance struggles. If they are on a cliff during their battles, on rare occasion, they will fall to their deaths. Their horns will break on occasion, but it is much more common for them to come away with nothing worse than a bloody nose.
Bighorns retain their horns, which continue to grow each year.
A. Bighorns have excellent eyesight and peripheral vision, which enables them to see predators from a long distance. This gives them time to escape. When a bighorn is threatened, it takes refuge on rocky ledges and cliffs where most predators cannot go. Both yellow and white collars are used. Ewe W5 was collared in on March 24, 1998.
