In the meantime, here's the remaining tern photos from Inchcape Park, Arbroath, taken on 10/9/2019. Both species were reported there again on the 11th. I've posted as many different views as I have, hope this helps you find one if you visit. You'll see just how the colours and tones are affected by the changes in light and background.

Being watched over by the Kittiwakes
There are two Roseates in this photo, marked if you can't see them with a red dot! The foreground bird doesn't have rings which is unusual for Roseate Terns, the rear one does
Perhaps the closest it came as the tide rose, just as a big cloud arrived, I'm sure they follow me around, the clouds not the terns
