Taken Lake Mattamuskeet,NC 27 Dec 2015. There were 2 Trumpeter Swans and several Tundra Swans. I tried to take photos which would demonstrate the difference in size and bill shapes. I also took several just because I liked the graceful way they could utilize their necks. Please note that in most of the photos including a Tundra you can see the yellow in front of eye. If you click on original under the first full photo, you will have larger more detailed image.
