To the best of my knowledge, the World Swan Calling Championships had never been won with a call until the Swan Song came along. It is traditionally a voice calling contest, and the boys (and girls for that matter) from NC are very good at it. My oldest son, Bonce was the first to put a win on the call in the Juniors in 2000. He repeated in 2001 giving him 3 wins including an earlier voice win. His brother Jacob won in 2004, 2005 and 2006, and Jacob Ogden won in 2008. In the Senior World Swan I broke the ice with a win in 2003. Dan Baker III won in 2005, and I won again in 2006 and 2007.
10 World Championships in the heart of Swan Country in NC is not an easy feat. I think it is proof enough however that this call has what it takes to reproduce the sounds necessary to call swans as well as judges!
