|The Macaroni penguin (Eudyptes chrysolophus) has a phenomenal 2,000,000 breeding pairs, mostly on the north-west of the island, particularly the Willis Islands. Macaroni's reach a height of around 2ft 4 inches (70cm) and weigh in at around 12lbs (5.5Kg). They typically lay two eggs, although only one chick is normally reared. The adults take turns incubating the eggs, and once hatched, the male broods and guards the chick while the female brings food.
The Rockhopper (Eudyptes chrysocome) does also breed here on occasion, and the first Adélie (Pygoscelis adeliae) breeding pair was discovered in 1997.
|The Antarctic Tern (Sterna vittata) nests on South Georgia. It is known that the Arctic Tern migrates South during the northern hemisphere winter, but not known if the reverse happens. Perhaps someone out there can enlighten me. The Tern is very good at defending its nesting site. If one goes near, the adult will divebomb; and the beaks are very sharp!|
