Bighorn Ewe and Lamb, WyomingBighorn lambs are typically born on steep, rocky cliffs — natural nurseries that help protect them from predators in their most vulnerable days. The ewe stays close, nursing frequently and guiding her lamb through increasingly difficult terrain as it gains strength. Within just a week, the lamb can scale ledges with surprising agility, always keeping its mother in sight. To see more maternal behavior from nature, check out the “Mother’s Nature” wall calendar I just added to my shop at www.specieslimted.com.
