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.
