A seawatch today in a freezing onshore wind revealed that there were large amounts of waders moving past west presumably having been frozen out from the continent, and although the majority of flocks were too distant to id to species, the ones that were closer were all Redshank with flocks of 20+ birds passing at a time, and were undoubtedly the most I had ever seen moving through the patch. Also moving west were a notable passage of Shelduck along with a few Pintail too.
