Another wonderful day out with the Pembs Ringing Group. This was a trip to Skokholm Island to colour ring Puffins as part of a research project for Oxford University (
E.G.I.).

Back to the boat after a very successful day out on Skokholm hoping this will be a valuable contribution to ongoing seabird research.
Good luck from Santiago de Compostela. I'll come back to Wales on 24th...
