Circus cyaneus cyaneus
Regular but very scarce autumn and winter visitor seen chiefly by snipe and duck shooters. Mathew records it at Rhinderston and Cuffern Mountain and believed it to be “resident, but becoming scarce” but it was quite probably confused with Montagu’s Harrier. Visits Skomer in winter but not recorded Skokholm. There are no definite records of it ever having bred in the county.
