It was then that Gene Herzberg spotted the otter near the far shoreline with a black duck in its clutches. I turned just in time to get one shot before the otter vanished under the sheet of ice and disappeared.
I included this last picture because it shows the duck in front with a darker wing with the white of its wing showing. Several pictures show this. At first look at my guide, I don't see an example of this. As time is short this morning, I will have to look this up later.
