Acrocephalus dumetorum – Telor Cyrs Blyth – Vagrant
Blyth’s Reed Warbler, Skokholm, September 2013
Blyth’s Reed Warbler is a bird which breeds from from Finland through to Siberia and winters in Asia. It has only been recorded in Wales on two occasions, both birds were trapped.
The first Welsh record was of one trapped on Bardsey on 13th October 2001
One trapped in the Cottage Heligoland on 27 September was the first for Skokholm and Pembrokeshire, and the second for Wales (TW, SW, RDB et al.). It was released in the Courtyard but was not seen again. A small body feather was sent for mitochondrial DNA analysis and was found to have a cytochrome b sequence between one and three base pairs different to Blyth’s Reed Warbler reference material but 57 base pairs different to any other species (M. Collinson pers. comm.). Although there were fewer records nationally in 2013 than in the preceding record year, there have now been low double figure counts for four consecutive years (although there were only seven accepted records in 2008 and 2009, four in 2006 and two in 2005).
