Some new ring read at Rewal from yeasterday. Both Herring Gulls (Larus argentatus) read by Piotrek Zientek. One from Polish project and the second German.
The whole life history of the X79C you can get at the green gull website. As you can see the gull was ringed in Germany and after flew to Denmark.
