Winter visitor and passage migrant. Not recorded in August and September
Mathew (1894) listed undated occurrences at Stackpole and Haverfordwest, and Lockley et al. (1949) added just one other, a female shot at Milford Haven on 7 December 1906. Between two and seven have been noted in 24 of the last 30 years, following one at Dale in mid-January 1958. Records refer to ones and twos settling in for the winter in St Bride's Bay, mostly off Newgale or Broad Haven, and the Amroth—Saundersfoot area of Carmarthen Bay. Others are seen in transit off headlands such as St David's and Strumble. Occasional 'mini wrecks' deposit singles, or groups of up to four, on fresh waters such as Llysyfran reservoir and Bosherston Pools and into the Cleddau Estuary (to the Gann mostly), where they sometimes stay for weeks or months. Up to 12 were in the Amroth—Saundersfoot area from January to March 1989.
