I finally got around to enter the details of my Sandling sightings today and got back the following information.
It was first ringed back on the 17 May 2010 in the North Atlantic? I am assuming by that the precise spot is not known rather than actually some where in the middle of the ocean.
It's a female bird and has the catchy name of G4WYWY ring number ISR 897008.
Here is hoping she has a great 2016, and best of luck to her.
