This report presents data on scarce passerine migrants recorded in Britain during 2013. As in the non-passerine section (Brit. Birds 109: 21-45), it was a record year for three of the species discussed here: Red-backed Shrike Lanius collurio, Yellow-browed Warbler Phylloscopus inornatus and Little Bunting Emberiza pusilia. The total of 2,191 Yellow-browed Warblers was extraordinary, an increase of almost 50% on the previous record, itself less than a decade old. There were three 'second-best' totals Dusky Warbler P. fuscatus, Red-breasted Flycatcher Ficedula parva and Parrot Crossbill Loxia pytyopsittacus and three third-best as well Woodchat Shrike Lanius senator, Greenish Warbler P. trochiloides and Marsh Warbler Acrocephalus palustris. Among the species doing poorly were Aquatic Warbler A. paludicola and Tawny Pipit Anthus campestris, with just one and four accepted records respectively; both species were readmitted to the BBRC fold from the start of 2015. Melodious Warbler Hippolais polyglotta and Ortolan Bunting E. hortulana are not in imminent danger of becoming national rarities but the latter in particular is a cause for concern: there were just 22 in Britain in 2013.
