Stercorcarius parasiticus – SGIWEN Y GOGLEDD – Passage migrant. The number of birds involved each autumn varied, extremes being 67 in 1993 and 355 in 1985. Differing breeding success no doubt played a part in this variability but changing weather systems seem to have been the main factor. Autumn totals at Strumble Head, 1980 – […]
Stercorcarius parasiticus – SGIWEN Y GOGLEDD – Passage migrant. The Arctic Skua has a circumpolar Arctic breeding distribution extending southwards to northern Scotland. Migrants seen passing through British waters are en route to and from Atlantic wintering areas, principally south of the equator. Mathew (1894) noted just one record of an Arctic Skua, shot at […]
Stercorcarius parasiticus – SGIWEN Y GOGLEDD – Passage migrant. Not recorded in February and March Mathew (1894) recorded just one Arctic Skua, but Lockley et al. (1949) commented that they were occasionally seen off Skokholm and Grassholm, usually in August and September, sometimes in May and June. This pattern continued to be recorded, but with autumn occurrences […]

It is more scarce on our south-western coasts than the Pomatorhine Skua, but a season rarely passes without one or two being noticed. Sir Hugh Owen has shot an immature bird at Goodwick. There […]
