CLOSED: Forster?

I got a few terns on this photo and was wondering if this was a forster tern? The adult and/or juvenile. The adult has a black bill

Yep, Forster's at front right. Left-hand bird might be a Cabot's Tern, but not certain.

Thank you on the Forster's new bird for me. I agree on the other bird, just can't tell.

Easily told in winter plumage by the dark eye patch; other terns have a dark rear crown, not eye patch. Much less easy in summer, when it is confusable with Common Tern.
