Tern id help please

Please advise if I am looking at a couple of juvenile common or other type tern?

Technical Details

Composite: No
ISO 800 f5.6 AT 1/2500 with 500mm

These are Caspian terms. The black on the head encompasses the eye, tail not deeply forked. Immature and winter adults resemble elegant and royal terns and the are not easily separated from each other. Nice photo by the way.

I was having difficulties as most of the tern photos I was seeing as examples had solid black caps even more pronounced than these. Although these were shot in Florida we don’t get many In southern Indiana. Thanks Jim, Appreciate the help!
