Red darvics on Med Gulls

PS - according to cr-birding.org, projects using red colour-rings to tag Med Gulls are, without exception, based in Eastern Europe (Czech Republic, Serbia & Montenegro, Lithuania, Poland, Hungary), so on balance this morning's Med Gull is likely to be from this region. Quite a common wintering strategy in easterngull populations.
