Stercorarius maccormicki

Transequatorial migrant, departing from breeding grounds in Mar and returning Oct-Nov. Many Northern Hemisphere specimens are of immature birds, as far north as Greenland, Japan and British Columbia. Wintering areas thought to be throughout North Pacific and North Atlantic, perhaps with clockwise loop migrations. Commonest Catharacta in May-Aug on Grand Banks of Newfoundland. Records from E North Atlantic few, and confused by presence of C. skua.
