Phylloscopus inornatus – Telor Aelfelyn – Rare autumn visitor
Yellow-browed Warblers were recorded in 15 years between 1959, when they first occurred at Skokholm on 2 October, and 1992. Single birds have occurred at the Smalls, South Bishop, Skokholm, Skomer, the Gann, St Bride’s, Manorbier, Castle Pill and Strumble Head, with two at the latter locality on 30 October 1986 and at Caldey on 14 October 1989. Dates of occurrence span 25 September to 19 November, with 70% falling between 2 October and 27 October. All were juveniles of the nominate Siberian race, presumably displaced by weather systems when heading towards wintering areas in south Asia.
