Rare visitor
Mathew (1894) noted that Black Grouse bones were discovered in Longbury Bank cave near Tenby in 1878. He concluded that the species must have been indigenous, but in his own time knew only of a few introduced at Trecwn, which did not survive long. The only records since have been of single females at Pantmaenog Forest, from January to March in about 1949, and on nearby Foel Feddau on 6 May 1971.
