Sitta europaea affinis
Mathew recorded only one, shot at Slebech, 7 Sept 1893. W.M.Congreve saw it at Picton and Saundersfoot in 1908. Now common in all wooded areas as a breeder, and wanders to small woods in sheltered valleys in exposed areas out of breeding season, eg Dinas Island and St Brides.
