Went down to Sheringham Bird Observatory straight after work for a wander before tea. No sign of any passerine migrants, a few Swallows were moving west along the cliff, probably going to roost. On the beach half a dozen Ringed Plover were briefly joined by a Sanderling. Just before the heavens opened a Shag flew west in tandam with a Cormorant, giving a good comparison.
