This bird was seen on rocks with a huge flock of semi palmated plovers, some Least and some Sanderlings and some Turnstones, after people walking on the sand beach in the fog startled the flocks up and onto the rocks. It was checking through the rocks/rock weeds on the side the waves were breaking onto the shore, rather than working in the sand, although that could be because it got flushed off the beach.
I have a suspicion what this is but I'd love another opinion.
