* 2002 Bird Report gives a date of 1st March. This was a typo, as the original record shows one singing 31st March at Milford Haven Golf Course, with a bird singing there on the 7th and 10th April too.
** 2017-18 One in a Kilgetty garden, from 12th Nov until 16th Feb (T. Hughes). This represents the first record of this species overwintering in the county.
Records extracted from the Pembrokeshire Bird Reports which may contain more detail.
