This is an Arctic Tern, also found on the Farne Islands. The scientists on the islands are very interested in these birds because of their long travels and interesting nesting habits. You can see this one has been tagged with a little ankle band. Hopefully you can also see that it wasn’t very happy that I was so near its nest.
1/800s f/5.6 200mm ISO 100. Cropped. Au revior until next week.
