觀察細節

Large, all dark bird with exception of two light colored spots (one in front of and the other behind the eye). Big, think bill. Took flight with some other ducks shortly after seeing it. Circled around, landed briefly then took off with other ducks. Wing all dark on top, no light/white patch. Unable to determine if they moved to another part of the reservoir or completely left. We glanced over at George's Run, following up with a check of the beach and dam. No ducks in sight.
