Hi Mike,
The Black Terns were put out on national Birdlines at 10:55 ( your picture post on here 15:44), a pair stopping to breed would be unlikely and the pair would have to be around for at least 4 days and I don't believe they would be able to keep it quiet on an RSPB Reserve just a watch set up.
John ...
I think Mike is looking for a 'yes' or a 'no' !
You've given him neither.
