Tennessee NWR Duck River Unit Pool 1 Humphreys County 08/06/12 I observed one of the immature tricolored herons in Pool 1 about 100 yards down the levee past the pump station. Thanks for the post Ruben. It is a life bird for me. Didn't really have time to search for anything else. Kicked the pump on one last time so fresh mudflats for shorebirds should be exposed my the morning. Clayton Ferrell
