This video is hard to explain but it cerainly has some exquisite choreography. Sophie Windsor Clive and Liberty Smith experience one of nature's greatest and most fleeting phenomena, a "murmuration" on Ireland's Shannon River. The pair created a short film about their amazing row and submitted it for the World Wildlife Fund competition "Life, Nature and You. Make the Connection." It's a magical moment.
