A Little Shearwater occupied a burrow on Skomer from June to August in both 1981 and 1982. It was identified as a male by its voice, and it brought nesting material to its burrow but apparently failed to attract a mate (James and Alexander 1984). Singles passed Strumble Head on 27 September 1982, 16 October 1983, 21 September 1984, 5 November 1989 and 7 October 1990, with two on 7 October 1988.
The Strumble Head series of records, coupled with others off southern Ireland, suggest visits to the area are sufficiently frequent for colonisation of the islands to be a possibility, Skomer evidently being suitable for nesting.
