Colour Ringed Black-headed Gull

A late afternoon visit to Little Marlow GP turned up a good variety of wildfowl but the only slight unusual visitor was a Shelduck which had been present for a couple of days.  As it was getting close to dusk I had a good look through the Gulls which were gradually building up in numbers.  There were good numbers of Black-headed, Common, Herring and Lesser Black-backed Gulls, plus three adult Great Black-backed Gulls.  In among the flock were two white colour ringed birds.  One was muddy and unreadable, while the other had the letters "AJ66", which appears to have been ringed in Germany.  Details are awaited.
