Yesterday I got nice recovery !
One of the BHG we ringed(it's Kreso's ring) on November 26, 2006 on Jakusevec rubbish tip was photographed in Yaroslavl. It didn't have plastic ring, just metal.
We're waiting for the whole ring number (one digit is missing). If I understood right this is crop from photo of gulls . It'most eastern recovery of BHG ringed on Jakusevec :) Distance is ~2083km.
Nice one :)
