Yesterday we received the details back on this Sandwich Tern that we had out on Terceira, Azores on the 8th february 2011. This bird was ringed as a pullus on the 01/07/2009 at Ujscie Wisky, Poland. This bird was wearing a metal ring and the code/ details were read by Olof Jonsson from Sweden whist he was out on the Azores 26/02/2011."Nice one Olof" and this shows that the reading of standard metal rings does pay off as with Vincent doing the same in Holland with Gull's.
