If you travel to the Buffalo National River in the Boxley Valley area near Ponca you will see the Old Mill Pond. This is where you will be able to see the Trumpeter Swans.
I don’t take many photos of them because of the large tags around the Swans neck as you can see in the last photo.

Trumpeter swans are increasing in Arkansas, and they are the focus of a multi-agency experimental program in parts of the state apart from little Magness Lake just east of Heber Springs, where they have been wintering since the early 1990s.
