Transcription: Big horn rams leave the winter herd in spring as they all move up to the higher slopes and pastures. The ewes follow separately. Food during the summer is mostly grasses. They come together again in the fall when the great headbutting spectacle for which these wild sheep are famous begins. Rams charge each other at 20 miles an hour and the crash of bone can be heard for miles. The winner gets the ewe, the loser walks away to just another day.
