About These Birds
Great Skua
Great Skua, 50–58 cm, wingspan 125–140 cm, is a powerful pirate of the North Atlantic, breeding in Iceland, Faroe Islands, and Scotland. Dark brown with white wing flashes. Attacks gannets and kittiwakes to steal fish; also kills other seabirds outright. Winters pelagically in the Atlantic.
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.
