Vagrant
Mathew (1894) quoted Sir Hugh Owen as the authority for the occurrence of Bearded Tits near Sealyham in about 1860. Up to ten were seen at Rosehill Marsh, on the Pembrokeshire/Ceredigion border, between 31 December 1973 and 17 January 1974 (M.A. Patterson et al.), a period when a surplus Dutch population was colonising Britain, Denmark and Sweden (Sharrock 1976).
