Scott Somershoe and I spent a few hours this morning birding at TN NWR, Duck River Unit (Humphreys Co.). Highlights were a single distant juvenile TRICOLORED HERON and a juvenile AMERICAN AVOCET, both in pool 1, viewed from the pumphouse levee. There were lots of SEDGE WRENS singing and readily visible. We counted 14, mostly at pool 3 with a few at pool 2 also. We didn't try very hard and there were likely many more. Otherwise, well over 100 CASPIAN TERNS and a few FORSTER'S and BLACK TERNS rounded out the list. The full list is below.
