About These Birds
Long-tailed Jaeger
Long-tailed Jaeger, 48–53 cm body plus up to 25 cm tail streamers, is the most elegant jaeger, breeding on Arctic and sub-Arctic tundra worldwide. Feeds primarily on lemmings on the breeding grounds; transitions to pelagic planktivore and piscivore on the ocean. Migrates to subantarctic waters — one of the longest migrations.
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.
