Two Bonaparte’s Gulls were seen at Cardiff Bay this morning, and the Little Gull, I believe at the road bridge end of the Bay. I and several others watched one of the Bonaparte’s at the Barrage end late morning,and the footless 2nd yr Med Gull was there too.

I was on the barage side and got shots of one of the gulls. Of the 100 or so shots, none show black marks on P9 and the head marking was much less than the bird Lol and I (and Peter yesterday) saw on Sunday – and photographed. This bird looks very like the shots Mark posted yesterday. I have put 6 shots on my web site along side Sundays bird and the Cossie bird in Jan last year.
