This is not a seagull. After visiting the beach near Cardiff and spotting a seagull swooping around with a fish in it's mouth I pointed it out to my wife.

She claimed it wasn't a seagull but in fact a pigeon. You know, those famous, huge, white pigeons that live in the sea.

I will be pointing out sea pigeons to her for a long time to come. I think she's lived in London too long.
