Stercorarius pomatorhinus (S pomarinus)
This species comes next in size to the Great Skua, and possesses in its adult plumage two elongated central feathers in its tail which broaden towards their tips. It is by far the commonest of the family upon our coasts, and a few are to be seen every autumn, and after heavy gales large flocks are observed. Dr. Propert possesses one, an immature bird that we have seen at his house in St. David's, that was shot on Ramsey Sound. Sir Hugh Owen has seen this Skua in Goodwick Bay, in all stages of plumage, and calls it "the most falcon-like of the Gull tribe."
