Saw this Gull yesterday with a Herring Gull in front of Morrisons in Barry.
Having a few doubts as to whether it is argentatus or Lesser black backed x Herring.
Still only the beginning of Feb and it`s in summer plumage, would have expected a little more streaking around the head this time of year.
My immediate thoughts were Yellow legged except the legs are pink and head shape wrong.
It was the same size as a herring with slightly darker mantle. Photos lead you to believe that the mantle is exceptionally dark but it was certainly a shade darker.
It flew before I could get any flight shots to see the primaries.
