Sylvia cantillans – Telor Brongoch – Vagrant
Single birds were seen at Skokholm on 1 October 1953, 3 May 1970, 7 June 1976, 11 May 1990 and 15 May 1992, and at Skomer on 20 April 1971, 19 April-8 May 1985, 20 May 1986, 26-27 March 1989, 3 and 26 May 1990 and 14 and 22 May 1992. A Mediterranean species that winters in sub- Saharan Africa (Cramp 1992) it sometimes over-shoots its range during spring migration. It inhabits dense scrub and is often secretive, so may be overlooked in the extensive cover of the mainland.
