While sailing on Woods Res. Friday 3/9, My wife and I watched an Osprey take a fish and fly off toward its perch. It disappeared into the treeline near the damn. A few minutes later we heard bird alarm sounds and looked back. An adult Bald Eagle was chasing an Osprey. Don't know if it was the original Osprey or not but the fish was not present.We slowed to watched the chase which lasted some ten minutes. Eventually the Eagle flew away and the Osprey quickly dove for the trees. John Sanders Petersburg, Tn Marshall county Observance took place in Franklin County tennessee
