Males were noted at Rosehill Marsh on 30th January 1972 (record not submitted to BBRC); at the Gann on 22nd – 27th April 1977 and 2nd March 1986 (Donovan and Rees, 1994).

2003 – One was at Little Milford 9th January.
2004 – One male at Lawrenny 15-16 February, and probably the same bird was also seen on North Pond Skomer on 25 January (4th Island record). Note that the original bird report entry has been corrected here from entries in the archive.
2005 – one was at Newgale 2nd to 12th December and Skomer 26th November, with two different males on the island on 28th November; probably three birds were involved altogether.

2010 – Two records this year both of males, at Marloes Mere from 8th to 25th April (WJ, PKG) & another at the Gann on 25th Dec (DJA). Both accepted by WRP and probably relating to the same returning male from last year
