A Snow Bunting this a.m. again but different to the 2 on 9th. A 1st yr male or ad female based on grey-brown in wing coverts. Again a bright bird with a lot of white in the outer tail particularly - in fact looking all white. I suspect these recent birds are not the darker Icelandic 'insulae' but 'nivalis' (pretty much everywhere else till Siberia and the even brighter 'vlasowae') . The Avifauna makes 'nivalis' very much the minority in Britain though without giving a reference.
