Bartramia longicauda – Pibydd Cynffonhir – Vagrant
Single birds have been seen at Skokholm on 18 October 1960 (K.Smith), at Skomer on 19 and 20 October 1961 (D.R.Saunders) and at Dale airfield on 1 September 1975 (J.W.Donovan), the latter bird being uncharacteristically very wary, requiring considerable persistence to confirm its identity.
