Records of Iberian Chiffchaff Phylloscopus ibericus in northern Europe are increasing. At the time of writing, all British records have been singing males. In this paper, we present sonograms of some accepted and potential Iberian Chiffchaffs from Britain. The characteristics of Iberian Chiffchaff song that can be used for identification of vagrants are reviewed. A record of a bird at Skelmersdale, Lancashire, in 2004, is thought unlikely to have been an Iberian Chiffchaff, but another bird, a mixed singer at Dibbinsdale, Merseyside, also in 2004, may be acceptable. The vocalisations of an accepted Iberian Chiffchaff in Oxfordshire in 2000 are now considered not to be absolutely typical. A problematic bird at Lavenham, Suffolk, in 2007 is also discussed and thought not to be acceptable.
