PR6T was then seen in Germany in December 2011 and this east-west migration of Caspian Gulls seems to be the norm. True to form PR6T was then recently seen again, but this time in The Netherlands, on Terschelling Island on 18th November.

Once again this highlights the kind of information that can be gained from colour-ringing studies, all of which rely on the support of the wider birding community in looking for and reporting these birds. Full details for this bird (and further photos) can be found on the North Thames Gull Group website, where you can also report any NTGG birds seen. Thanks to Paul Roper from the group for passing on this story and for the photos of he bird in the hand, and to Jacob de Vries for the photo of the bird in The Netherlands.
