TN NWR Duck River Unit Duck River mudflats Humphreys County 09/03/13 One American avocet in non-breeding plumage on the recently exposed mudflats, feeding near 18 N. shovelers. Numerours other shorebirds present but looong distance and heat waves made ID a challenge. I did for sure see least sandpipers, pectoral sandpipers, and semiplamated plovers which I kept wanting to make one out into a piping plover as it appeared lighter than the others. Dozens of black-bellied/ golden plovers. The white seperation line was all that I could see clearly so to speak. Struggling to decide which one as some were in full non-breeding plumage to half and half. Again distance and heat waves were a major issue as was the crappy tripod I was using! LOL I will bring my sturdier personal one tomorrow! No use trying to view this spot in the morning as the whole area is backlit by the morning sun. If anyone is interested in checking the area out i can give you more details on how to get there, but I will first say that it is a 9/10 of a mile hike down the levee. Then a short hike through thick habitat in which I would recommend knee boots as it is an easy place to step on a cottonmouth, then slog about 75 yards through boot sucking ankle deep mud and a narrow slough of water near the top of my boots. Lake level rose several inches between the morning and afternoon. Clayton Ferrell
