Herring Gull (argenteus) YAFM adult female, 2009-2010, IJmuiden, the Netherlands. 

Ringed Herring Gull Y.AKS from Forteiland, IJmuiden. Ringed by Fred & Kees as breeding adult on the nest on May 25 2009.

The IJmuiden Ringing Team (Fred & Kees) have ringed again several Herring Gulls and Lesser Black-backed Gulls at Forteiland, IJmuiden in 2008-2011. This time green darvic rings have been attached, starting with Y for borh species (so codes read Y.xxx).
Early in the seasons (May), adults are being caught at the nests and ringed, late June several juveniles are being caught and ringed as well.

This page shows an example of birds from this IJmuiden project. All observations of ringed birds from this project can be sent to Kees Camphuysen at NIOZ, Texel (mail camphuys at nioz dot nl).
