Abstract

This report summarises the scarce passerine migrants recorded in Britain during 2008-10. Three good years for Red-rumped Swallow Cecropis daurica (the second-, fourth- and sixth-highest totals) continued the trend towards increasing numbers in spring while, from the same region, 33 Subalpine Warblers Sylvia cantillans in 2010 represents the second-highest total on record.
