After 2009’s exceptional ringing coverage and numbers of birds ringed, 2010 saw a return to more normal levels. The most remarkable feature of the year was the variety of birds caught: 62 species, making it the best since 1997. Migrant birds were ringed during one week in spring and five in autumn. There was additional coverage of one week in February and one in June, and Manx Shearwaters were the focus of attention during two weeks in early autumn. In all, 2,494 birds were ringed.
More than 500 migrant Chaffinches were ringed in late autumn, and Blackcap numbers also topped 500, as a result of good passage in both spring and autumn. A total of 190 Manx Shearwaters were ringed, mainly due to another record year for chicks. Other species with totals over 100 were Swallow, Chiffchaff, Willow Warbler and Blackbird. After 24 Stonechats were ringed in 2009, the drop to just a single bird in 2010 is a concern; it is likely that mortality was high in the intervening cold winter. In contrast, recent worries about the island’s Dunnock population have eased, with ringing providing evidence of reasonable winter survival and a good breeding season. Numbers of autumn migrant Goldcrests also increased, after a very poor showing in 2009, suggesting better breeding productivity in Britain.
Among the unusual species ringed, there were eight for which Lundy’s 1947–2010 grand totals are still in single figures: Merlin, Great Spotted Woodpecker, Nightingale, Red-flanked Bluetail, Mistle Thrush, Western Bonelli’s Warbler, Hawfinch and Lapland Bunting. Also notable were four Treecreepers and two Common Rosefinches. A full list of the year’s ringing totals appears below.
An interesting selection of recoveries and controls includes a Manx Shearwater which was ringed at the colony on Copeland, off Northern Ireland, in 2005 but has almost certainly settled as a Lundy breeder. Now that shearwaters are breeding successfully on Lundy, their numbers are building up so fast that some immigration must be involved; this individual, probably ringed when it was a young pre-breeder, gives the first hint of their origins.
While Lundy’s Lesser Black-backed Gulls are regularly seen wintering in Portugal, the 15-year-old Herring Gull found there is exceptional. A Chiffchaff and a Blackcap, both ringed on autumn migration, also went to Portugal. In contrast, a Firecrest and a Redwing wintered in the British Isles and probably became victims of severe weather: they were found dead in Cornwall and Ireland respectively. Details of these and other recoveries are given in the relevant species pages.
