Gulliver

Gulliver and his partner Josefine are still visiting the balcony daily, but both are meanwhile molted into complete winter plumage.

In a way it's easy to tell Gulliver apart from the other neighborhood gulls, thanks to his attitude and the fact that he rarely leaves the side of Josefine. But when in doubt, we check the iris. The black specks on the yellow eyes form a unique pattern, almost like a biological "barcode". And during winter season the pattern formed by the stripes on their head is another way to tell apart individuals.
