Strong migratory; winters in the North Pacific and North Atlantic, crossing the equator. Polymorphic; feeds on penguins, fish, and krill. Circumglobal migration.
Pomarine Jaeger
Pomarine Jaeger, 46–51 cm plus twisted spoon-shaped central tail feathers, is the largest of the three small jaegers. Breeds on Russian and Canadian Arctic tundra; lemming-dependent on breeding grounds. Heavily built; pirates food from other seabirds at sea and scavenges at whale carcasses. Pelagic in winter.
