It’s not the son but a Common Tern that my wife and I saw down at the Duluth Harbor. We had gone for a walk and ended up along the harbor wall. I noticed a bird flying towards me and thought it was probably a gull but as it came closer the sharp definition of the wings made me realize it was a Common Tern. I kicked myself for not having the camera ready. However, the Tern flew past us and made a sweeping turn and flew back down the harbor. Soon I noticed it flying back toward us along the harbor wall. It was fishing for small fish. We watched it for about twenty minutes as it repeated the process before flying off.
