On the 28/01/10, I sent in ring sighting, using this and other photos, through BTO/Euring for this Sanderling at South Beach, St Mary's Island
The correct ring pattern is as per sketch below

I received a reply dated 31/01/2010 from Jeroen Reneerkens pictured below. The Sanderling had been ringed by him at Sandgeroi in Iceland on the 20/05/09.

Subsequently it has been sighted
St Mary's Island - 09/09/10 through to
St Mary's Island - 28/01/10
Jeroen Reneerkens blog tells about his research in Greenland and Iceland with Sanderling and you really must play the video titled 'Julia...' on the first page - incredible.
Information about Jeroen's research into Sanderlings can also be found at Wader Study Group website
.....and we trust the journey still has a long way to go.
