Ringed Lesser Black-backed Gull Y.ARX from Forteiland, IJmuiden. Ringed by Fred & Kees as juvenile on July 05 2010.
The IJmuiden Ringing Team (Fred & Kees) ringed Herring Gulls and Lesser Black-backed Gulls at Forteiland, IJmuiden in 2008-2011, using green darvic rings, starting with Y for borh species (so codes read Y.xxx).
Early in the season (May), adults have been caught at the nests and ringed, late June the juveniles were 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).
Completely juvenile.
