Just Another Gull

My apologies to Kilchoan Early Bird who sent me this picture on Christmas Eve. I wrote it off as 'just another gull' but it isn't - it's a rare glaucous gull, of which the RSPB says there are only 170 individuals in British waters, and then only in winter.

It's a large gull, the second largest in the world, and it breeds in Arctic regions in the summer, migrating south for the winter.
