Belated report, but I spent the evening of 31 Jan 2012 at Cook Rec area on the east side of Percy Priest Lake (Davidson Co.). Majority of loons were gone (26 total), NO horned grebes, very few ducks and ring-billed gulls, but LOTS of Bonaparte's Gulls. I had a flock on the water that eventually got up and flew by. I estimated numbers as they flew by and totaled 2400, plus several hundred more seen flying in off Anderson Rd. I estimated 2900 Bonaparte's Gulls, which is my second highest lake count, and is certainly a low estimate. Couldn't pick out a goodie in the bunch, I tried.
