The seagulls in Vigo follow the ships out of port for several miles. I'm not sure if they get extra food like that. It seems to be a game in which seagulls try to out-position each other. Needless to say it's tricky getting a good photo of them. Last time we were in Vigo I got about 100 shots of sky with an unidentifiable blurry object.

Here's the seagulls are bedecked with bunting as befits a page in my ABC of European Cruising album and we have humans on the rail vying for space:
