Numenius arquata arquata
Mathew had “little doubt” that it nested on Prescelly Mountain, and also “occasionally” on Skomer.
It is an abundant visitor to the coasts, especially in autumn and winter. Before the early 1930s it was not common as a breeder, but it has greatly increased and now nests throughout the county, except the Castlemartin peninsula. Large flocks resort to the islands during the moult, and it breeds frequently Skomer and Ramsey. Most numerous as a breeder in the mountainous northern half of the county.
