BB May 14 coverBB eye Citizen Action for Swifts Report on scarce migrant birds in Britain in 2008-10: passerines This report summarises the scarce passerine migrants recorded in Britain during 2008-10. Three good years for Red-rumped Swallow continued the trend towards increasing numbers in spring while, also from southern Europe, 33 Subalpine Warblers in 2010 represents the second-highest total on record. The fortunes of warblers with Siberian origins were mixed: increasing numbers of Yellow-browed Warblers maintained the trend apparent since 2000 and Radde's Warbler had three impressive years, whereas fluctuating numbers of Pallas's Leaf Warblers showed no pattern and annual totals of Dusky Warblers were poor. Other species faring poorly included Aquatic Warbler, Tawny Pipit and Rustic Bunting, which are now among the rarest birds considered in this report. First British records of 'Eastern' and 'Western' Subalpine Warblers The recent proposal to reorganise the taxonomy of the Subalpine Warbler complex, and the identification of the first British 'Subalpine Warbler' (St Kilda, June 1894) as a Moltoni's Warbler, led the BOU to review other early records and determine the first British records of both Eastern and Western Subalpine Warblers. DNA analysis together with morphological criteria showed that the first Eastern Subalpine Warbler was shot on Fair Isle in May 1908 and the first Western Subalpine Warbler on the Isle of May in May 1924. When do falls rush in? The timing and frequency of falls in north Norfolk and Fair Isle Records of falls of thrushes in north Norfolk in autumn, and falls of all passerine species on Fair Isle in both spring and autumn, were analysed to establish dates and frequency of falls. A total of 106 days of recorded thrush falls in north Norfolk during autumn, for periods dating back as far as 1880, shows that these occur most frequently in the second half of October. A total of 839 falls over a 60-year period for Fair Isle shows that falls occur throughout both spring and autumn but are more than twice as frequent in autumn.
