OK, slight exaggeration, but if you can see a Skimmers toes, you are very close.
All the fishing was being done at about twice the distance until this one turned towards the berm.
I now know they will follow each other, probably in hopes a small school of fish had been found. Knowing this should help me avoid surprises like this in the future.
The bird above has a small (tiny) fish. Not a great shot, but the fish helped the image become a keeper.
