I think this may be a Sandwich Tern observed June 8, 2023. I've never seen one here before or since. Thanks for your input.

Yes, Sandwich Tern - although I guess in Florida it could be a Cabot's Tern but I wouldn't know how to tell them apart.

Some confusion in naming. IOC recognized Cabot's as a species but Clements and Amer. Orn. Soc. consider Cabot's to be a subspecies of Sandwich tern.

The (proposed) split is primarily on geographical lines. The* subspecies of Sandwich that was found it North America is (proposed to be) promoted to species level. No need to tell them apart by plumage unless you suspect an extreme vagrant.

* Actually, two subspecies. The "Cayenne" population lives in the Caribbean and looks a little different. Depending which authority you follow, it's a subspecies of Cabot's, or not recognized at all (merged with Cabot's as a single subspecies of Sandwich), or possibly a full species.

Thank you. I was working on my eBird checklist. Cabot's Tern isn't on the list - so using Sandwich I think is fine. It is a new species for me, so I appreciate your help!

It was interesting to read what you said. I've learned a good deal more about terns, and really appreciate your input. Thanks!
