Black-headed Gull with white colour ring on right leg with code "AJ66". This was ringed in Germany (Helgoland) on 12 June 2015 and was seen at Little Marlow on 7th December. See my previous post.
Black-headed Gull with white colour ring on right leg and code "507". This bird was ringed as a 3rd calendar year + female on 27 March 2011 in Svanemollebugten, Copenhagen, Denmark. It has subsequently been seen in Denmark several times and at Little Marlow during the winters of 2012/13, 2014/15 and 2015/16. It is incredible how this individual returns to Little Marlow!
Herring Gull with orange colour ring on left leg with code starting with the letters "G9". There were presumably one or two more characters but these could not be read. However Adam Bassett contacted me to say that me had also seen this bird and the ring was "G9MT", another bird from the North Thames Ringing Group.
Dave left about 16:30 and I carried on searching through the gull roost. I came across the adult Mediterranean Gull but it was on the far side of the sand spit and only it's head could be seen. I did notice that the number of larger Gulls was higher than previous evenings and on another scan through the mass of birds, I came across the same Glaucous Gull that I had previous seen on 27th February (link to post). The bird was still present until 17:45 at least by which time Paul Watts had joined me.
