X Mediterranean Gull ?
by Martin G and Nigel Lound
“The attached gull was on the beach on 30th July 2012 in the evening between Skegness and Gibraltar Point. Surely has to be a Common/Mediterranean Gull hybrid? There seems to be little info anywhere (books or internet) on such hybrids and the little info I have gleaned on such hybrids always refer to “bill similar to Med Gull, dull red with black subterminal ring and yellow tip”. This is nothing like the Common Gull bill and legs shown by this bird. I didn’t manage any flight shots. It was a bit of a loner, only loosely associating with Common Gulls and Sandwich Tern, spending much time asleep. Whatever, it is a stunning looking gull.”
It would be interesting to know if and how the sex of the parents (e.g. was the presumed Common Gull parent, male or female) affects the appearance of a bird like this.
