Friday March 29 1:00 PM Swan Lake at Dunbar Cave has been exceptionally quiet for waterfowl this year, so it was particularly gratifying to see 12 Redheads today. Last weekend a pair of Bufflehead came by briefly. Otherwise, we have had scant numbers of Canada Geese and three Pied-billed Grebes keeping us company. Steve Routledge Clarksville/montgomery Co.
