Sylvia undata – TELOR DARTFORD – Vagrant
Single birds were seen on Skomer on 14 September 1971 (P. Corkhill) and at Skokholm on 1 and 2 June 1981 (G.G. Gynn). They breed as near as Hampshire and Dorset, where they inhabit heathy areas similar to parts of Pembrokeshire. However, the south of England is at the northern limit of their range, the majority residing in a much drier climate, suggesting that Pembrokeshire might be too wet for them to colonise.
