Antarktik Fırtınakuşu Thalassoica antarctica

Striking brown-and-white petrel of Antarctica and its adjacent seas and islands. Essentially unmistakable, but worth comparing with Cape Petrel if seen at great distance. Breeds on rocky slopes and cliff faces, both coastal and inland; one of very few flying birds likely to be seen any distance inland in Antarctica. When not breeding, disperses north, sometimes getting as far as the Falklands. Often seen in huge numbers around foraging cetaceans or fishing vessels.
