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.
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.
