About These Birds
Brown Skua
Brown Skua, 52–64 cm, is a powerful sub-Antarctic predator breeding on islands from the Falklands to New Zealand's subantarctic islands. Dark brown throughout; massive hook-tipped bill. Predates penguin and petrel chicks; piracy and scavenging common. Winters at sea across the Southern Ocean.
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.
