Fortunately, Jean-Michel is visiting the colony as often as he can, taking cracking images and reading metal rings when the colour rings have gone lost. I have added another 112 images taken by Jean-Michel, and I have to say every picture is a beauty!

You can check from the ring page and go to the Frech red rings: http://www.gull-research.org/lbbgjanmay/000rings.html
Or just start in any section like adult LBBG in March-April: http://www.gull-research.org/lbbg5cya/05cyapril.html
This last link also brings you to an outstanding work called "A historical ecology of two closely related gull species (Laridae): multiple adaptations to a man-made environment" - by: Kees (C.J.) Camphuysen - Ph.D.-thesis, University of Groningen, Groningen, The Netherlands, June 2013
And finally, I've uploaded some flying birds of all age classes for July: http://www.gull-research.org/lbbgjunjul/04cyjul.htm
