Unfortunately not head-on, but some indication of how bright the marginal coverts appeared in flight, as was mentioned by @aberladybirder.bsky.social, this afternoon - not sure how significant this might be, in this plumage, though...

Looks to me like green on left for Tyninghame bird, so a different bird - makes one wonder how many adult Black Terns there are north of the Humber, at the moment, and how many of those carry green rings....

Any ring details from your photos?

The Long Nanny American Black Tern bears a green ring, doesn't it?
