I´m new in this great forum. I come from northern Germany, near the danish border. Last Saturday I saw a ringed caspian gull 1cy and I couldn´t find any information about the project. Has anybody an idea? Could it been ringed by Norman Van Svelm, he uses green rings but lacks information which codes are used. Here is the Gull (Green ring/white code XVAU/bottom to top):
