TN-birders, Dollyann and I were going to go down to Chickamauga dam (Hamilton Co.) in Chattanooga today to try to find the White-winged Scoters that have been seen there recently. When I checked TN-bird this morning I saw where Colin Sumrall had a Long-tailed Duck (LTDU) out at Concord boat ramp (on Northshore Drive) in west Knoxville, Knox Co. We decided to try for it first. He had the duck at 8 am and we got there at 10 am. True to our luck recently chasing unusual birds, we could NOT find the Long-tailed Duck after about 30 minutes of searching. So we drove down to the dam and found 2 White-winged Scoters right at the dam, mixed in with a nice flock of Redheads, Lesser Scaup, and American Coots. Since we were in the area, we also checked out the Webb Road embayment and saw nothing of interest there. Same at Booker T. Washington Park and Harrison Bay (all locations in Hamilton Co.). Few birds at both those places except lots of Ring-billed Gulls and some Bonaparte’s Gulls, plus the usual scattering of Pied-billed Grebes. On the way back to Knoxville we decided to check in at the Concord boat ramp one more time to see if we could re-locate the LTDU. We got to the boat ramp about 3:30 pm and started scanning the lake. I have never seen an area of water that large as smooth as it was today. With zero wind it looked like a giant mirror and the viewing conditions were awesome. Dollyann was scanning with the scope when she found a winter- plumaged adult Red-throated Loon. We watched it for about 15 minutes and started calling some folks to get the word out, when the loon got up and made several circles around the area and then flew out of sight. So we then called the same people again and said don’t bother coming out, the bird has flown. Disappointed we couldn’t get anyone else on the bird, but elated to have seen it, I started scanning again for the LTDU, when I came across another loon that was not a Common. After looking at it for a while we determined that it was a Juvenile plumaged Red-throated Loon. So we (you guessed it) started calling folks again! Chuck & Lola Estes from Oak Ridge and Beth Schilling eventually joined us to try to find it, but by the time they got there the second Red-throated had flown off not to be seen again. DRAT! I hate when that happens. When Chuck & Lola got there we were scanning the lake again from the Concord boat ramp when I spotted an adult Bald Eagle flying over close to the sailboat marina on Northshore Dr. It eventually landed in a tree on that side of the lake. Scanning some more, Chuck eventually found a “darker than normal” duck in the same area. We both thought scoter of some kind and we got in the cars and drove over to the area on Northshore Dr. where there are twin bridges. One bridge is an old bridge that is now closed to traffic and used for fishing. It’s a good area to scan the lake. While there, we re-found the dark duck and it turned out to be a Surf Scoter. We eventually drove back over near the entrance road to the Concord Marina (the normal marina, not the one with sailboats only, which is west of the twin bridges) to see if we could get a better look at the scoter but could not re-find it. We finished up back at the Concord boat ramp where we ran into Mike Ryon and Dean Edwards and about 5,000+ gulls roosting on the water. An intriguing day to say the least, even if we did drive about a million miles! Both the Red-throated Loon and the Surf Scoter were new Knox County birds for us, raising our county total to 211. Great birding to all, Ron Hoff & Dollyann Myers Clinton, TN
