South Polar Skua
Stercorarius maccormicki
Skuas and Jaegers
At a Glance
It occurs regularly off both our coasts, but this predatory seabird nests only far to the south of us, around the edges of the Antarctic continent. When it reaches North American waters it remains far offshore, pirating food from other seabirds or catching its own fish.

Open Ocean
Parasitic Jaeger
Stercorarius parasiticus
Skuas and Jaegers
At a Glance
This is the mid-sized member of the jaeger trio, and the most familiar, as it is the one most likely to be seen from shore. Variable in plumage, it occurs in dark, light, and intermediate morphs.

Great Skua
Stercorarius skua
Skuas and Jaegers
At a Glance
A big, broad-shouldered, predatory seabird of the North Atlantic. Usually solitary at sea, although concentrations may occur where food is abundant. Breeds mainly in Iceland and on islands north of Great Britain; in North America, very seldom seen from shore, although it may be common far offshore during the winter. Closely related forms are common in the Southern Hemisphere, mostly in subantarctic regions.

Pomarine Jaeger
Stercorarius pomarinus
Skuas and Jaegers
At a Glance
Powerful and fast-flying, a predator and pirate of the ocean and the far north. The largest of the three jaeger species. Not seen from shore as often as Parasitic Jaeger, but usually the one seen in greatest numbers on boat trips offshore. In northern Alaska, this is a major predator on the brown lemming: During summers when these rodents are in low numbers, many Pomarine Jaegers do not attempt to nest.

Long-tailed Jaeger
Stercorarius longicaudus
Skuas and Jaegers
At a Glance
A swift-flying seabird, extremely graceful and agile in flight. When swimming, it floats buoyantly, and it takes flight from the water easily. Of the three jaeger species, the Long-tail is the smallest and the one that migrates farthest offshore; south of the Arctic, it seldom comes within sight of land.
