Antarctic Tern

Antarctic Tern (南極燕鷗)
French Australia and Antarctica Territories (2015)
1st January, 2015. Dumont D’Urville

Antarctic Tern is a typical tern. It ranges throughout the southern oceans. It is very similar in appearance to the closely related Arctic tern, but is stockier, and the wing tips are grey instead of blackish in flight. It is, of course, in breeding plumage in the southern summer, when the Arctic tern has moulted to its non-breeding plumage.

Breeding takes place from mid-November to early December. Chicks hatch from December to February. Skuas and jaegers are the primary predators of this bird's eggs and young.

The total global population of this bird is around 140,000 individuals.
