Being only forty miles away, I twitched to Damien's report, arriving at Pickwick State park around 5. Around 6, I finally spotted two athya ducks in mid-river. One of them did look very white on the sides, but at that distance I couldn't say much more. So, it may still be there, but I couldn't verify it. The two ducks were loosely asociated with a raft of 8-10 grebes, which I couldn't hope to identify further at that distance. A female bufflehead flew in at one point and joined them. The white slash on the head made that one IDable. I did find one eared grebe just off the beach parking lot, beginning to molt and showing some of the fluffy golden feathers. In the slough leading to the marina was a horned grebe in winter plumage; and another horned, showing the golden eyebrows, up near the bridge. There were at least six common loons in breeding or near breeding plumage - gorgeous birds. I did not see the red-throated loon or any scoters. I observed from several vantage points from the marina slough around to near the bridge. I also looked from the observation deck at the north end of the dam. Jud Johnston Waynesboro, TN
