French Med gull at Cemlyn

After the Polish Warsaw 1st year bird at Cemlyn last year there's now a 2nd summer bird which was ringed as a pullus in 2009 just east of Calais, France. It has a green ring with W89 in white on it. Recently there has been 2 adults, 3 2nd summer and 2 1st summer birds coming and going. Apparently they've been breeding in Delamere forest for three years with upto 3 pairs recently so they're obviosly doing well colonising the UK and Eire now.
