Bighorn ewe (Ovis canadensis) with its newborn lamb high on a rocky clifff wall. Note the mother's steadfast demeanor while the lamb is clearly aware of the photographer. Ewes select an isolated, sheltered site with unobstructed view to give birth. Usually single young are born, but twins have been recorded. Ewes keep the lambs in this cliff environment to protect them from predators. Lambs are weaned by 6 months of age.
