I was really surprised when I received an email from Michal Porteš. He photographed the first ever LGGB ringed in Croatia and found abroad :). It was orange 60BH I ringed last winter during the IGM and found in Vysoka Pec, Ustrecky, Czech Repoublic some 560km from ringing site :)
Here's the photo
On Friday I went to Jakuševec to see if there are enough gulls to go to the tip..
There were at least 15 LBBG there..
