Herring Gull (argenteus) Y.ADH 1CY, 6CY & 10CY, August 2008, June 2013 & May 2017, the Netherlands.

Ringed Herring Gull green Y.ADH from Forteiland, IJmuiden. Ringed by Fred & Kees as juvenile on June 30 2008.

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