The Bay of Isles is a bay 9 miles (14 km) wide and receding 3 miles (5 km), lying between Cape Buller and Cape Wilson along the north coast of South Georgia. It was discovered in 1775 by a British expedition under James Cook and so named by him because numerous islands (at least twelve) lie in the bay.[1] Of South Georgia's 31 breeding bird species, 17 are found here.
