Lesser Black-backed Gulls K.BAT and K.BAX, juveniles from the Vliehors project on Vlieland, the Netherlands, ringed as pullus on July 17 2007.

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

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.
