This is a larger species than S. crepidatus, hut similar in plumage, except that the cap is blackish and without any whitish frontal margin, and that the throat and collar are more strongly tinged with glossy brownish yellow ; there is some white barring on the hind neck behind the collar, and the lower fore neck, upper breast, and lower abdomen are dark brown, more or less barred and mottled with white. The middle tail-feathers, too, are blunt and rounded at the end, not pointed. Dark forms also occur, as in S. crepidatus.
Bill horn-brown, bluish on the cere; irides brown; legs and feet black.
Length 21; tail 5.25, the middle tail-feathers 2 to 4 inches longer; wing 14 ; tardus 2.2 ; bill from gape 2.
Distribution. The Pomatorhine Skua breeds north of the Arctic circle, but ranges widely in winter, and has been shot in Australia, South Africa, and South America. A single specimen was once obtained by Col. Tickell at Moulmein.
A single specimen of the Antarctic Skua, Stercorarius (or Megalestris) antarcticus, was brought alive to Major Legge at Colombo, in Ceylon, but under circumstances which made it doubtful whether it had been captured in the island (Birds Ceyl. p. 1050, footnote). This Skua is a large bird, with a wing of about 16 inches, dark brown above and paler brown below, inhabiting the Southern Ocean.
