On October 4th 2014, Paul Veron (http://guernseygulls.blogspot.pt/) joined Pedro Moreira and me on a ring-reading trip to the landfill of Eirol. Due to the surprisingly large number of gulls present at the site (15 – 30.000) a record amount of rings were read. More about this event can be found on Paul’s blog in some time from now. Among all these birds was a single Herring Gull Larus argentatus.
