Last week in Yellowstone, this Red Fox was the hunter, not the hunted. It was fascinating to watch her mousing. She would cock her head listening for a vole under the snow, then she would leap into the air and land face first deep into the snow emerging with the vole protruding from her jaw. Once she had made her catch, she would pace deliberately across the snow, deposit the prey into a snow bank for a future feast, mark the place by urinating, and go back to mousing again.
