Dall sheep (Ovis dalli dalli) young, called lambs, are born in late May or early June. As lambing approaches, ewes seek solitude and protection from predators in the most rugged cliffs available on their spring ranges. Ewes bear a single lamb, and the ewe-lamb pairs remain in the lambing cliffs a few days until the lambs are strong enough to travel. Lambs begin feeding on vegetation within a week after birth and are usually weaned by October. Normally, ewes have their first lamb at age 3 and produce a lamb annually.
