Possible Cinnamon Teal on Taff Rd. near Cartersville, GA. Aside from being rather reddish, the bird looked to have a large bill compared to nearby BWTE and was on the large end of the spectrum among the ducks present (at least indicating a drake, coming out of eclipse plumage). At one point I caught a glimpse of what looked to be red color in the eye, but the distance was challenging in the waning light. Although there were a number of BWTE present with quite a bit of reddish warmth in their plumage, this bird clearly stood as an outlier from even the extremes of the BWTE distribution present (visible even in the unzoomed photos). After doing some research, I don't think a hybrid with BWTE or hybrid backcross of (BWTE x CITE) X CITE can be ruled out given the lack of available data for such birds in eclipse plumage.
