TN NWR Duck River Unit - Pool 3 Humphreys County 07/02/13 Heard a sandhill crane calling continuously for about a minute as I believe it was flying around over the Pool but never could locate it. I was in another pool several hundred yards away. The call eventually faded off into the distance so no telling where it went. Pretty good shorebird habitat present in the pool for early migrators but for now only killdeer were seen. Also observed a male goldeneye in Pool 6 but this is more than likely a cripple.
