The Sandwich Tern at Ynyslas with the blue ring ETJ (see photo posted on 2nd August) had been ringed on 15th July 2014 at the Ythan estuary, Newburgh, Aberdeenshire and was judged to have been at least 2 years old. It had not been recorded anywhere else since then.
That is the second Sandwich Tern I have seen in recent years at Ynyslas which had been ringed there.
