Strong migratory; winters in the North Pacific and North Atlantic, crossing the equator. Polymorphic; feeds on penguins, fish, and krill. Circumglobal migration.

Arctic Jaeger

Arctic Jaeger (Parasitic Jaeger), 41–46 cm plus tail, is the commonest jaeger, breeding across Arctic tundra and wintering in tropical and subtropical seas. Highly piratical; pursues terns and gulls relentlessly to steal fish. Polymorphic: pale and dark morphs occur. Circumglobal migration through all oceans.
