07/13/11 TN NWR Duck River Unit Humphreys County Clayton Ferrell The three sandhill cranes are back! Actually I doubt they ever left but were "hiding". This morning just after six they were feeding in Pool 2 just off the Blue Goose auto tour loop. They were not seen there after lunch. There are plenty of mudflats around for shorebirds, but they are few and far between. Killdeer outnumber all other speceis combined.
