Strumble quiet AM, fall of Alba Wagtails Fishguard Outer Breakwater PM

Funny day today, a look around Strumble early this morning was uneventful bird-wise although quite a lot of Gannets travelling west, perhaps displaced by yesterdays strong winds. Apart from a couple of swallows and odd pipits coming in  there was little sign of migration until I saw two groups, each of half a dozen Goldfinches arrive!
I was not particularly expecting much from the outer breakwater but was surprised to find "alba" wagtails flitting about all over the place, at least twenty probably more. A small crevice had collected some rainwater and attracted the Wagtails who were obviously thirsty and in need of a wash and brush up? Really smart birds I think they should really be called silver wagtails!
