Hola Toño, igual me expresé mal, pero la gaviota está anillada en Bélgica, y esto es lo que me contestan los anilladores:

"We have been studying the pictures carefully. For the moment we are thinking of a fuscus-michahellis hybrid. Parents are noted as fuscus, but very probably there has been some (earlier) hybridisation with yellow-legged or herring. So, a very interesting individual. Also, herring gulls from our colony have never been observed during winter south of Bretagne in France. A bit of a mistery.."

Ya ves...
Saludos
