Early morning and late evening often creates otherworldly reflections on bodied of water. Such was the case one morning at Yellowstone's Floating Island Lake, as the early sun hit the opposite hillside. We had been waiting for wolves to return to a carcass across the lake (they did), but this lone swan provided a much better subject on the "golden pond." If your photographing a swan and its preening its feathers, as this one was, keep watching through the viewfinder as it will eventually rear back and stretch its wings.
