The same tern as previously uploaded. Thanks to all those offering an ID.
No interactions present.
So it was actually quite a large Tern! It would have been good to have edited the other posting with these pictures, to correct that identification.
My Flickr photos...
Apparently so. But alongside the much larger Royal Terns and Laughing Gulls that were present, it did seem small. I tried to edit the previous observation, but couldn't include the extra photos. Not sure what I was doing wrong! Anyway, thanks for the comment.
Lat/Lng: 26.4362, -82.1243
The bird was feeding off the shoreline with a number of other larger terns (Sandwich and Royal).
