About These Birds
Chilean Skua
Chilean Skua, 52–58 cm, is a large, heavily built skua of southernmost South America and Cape Horn islands. Warm reddish-brown tones, pale face. Predator and scavenger at penguin and cormorant colonies; piracy also common. Partially migratory; winters at sea in the Pacific and 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.
