A gull was photographed last Tuesday when it flew past Cap-Gris-Nez (France) and it was believed to be a Mediterranean gull. Pictures are now spread and some think it to be a Franklins (or even Laughing-) gull.
The overall apearance is very Franklins like (imho) but when you check the features of the bird they point towards Med gull. So honestly, I don't really know what it is, I tend to go with the first impression that it is a Franklins.
Your opinion please, in Holland the leading opinion is that it's a Med gull..
