Site description Bird Island is located 3 miles (4.5 km) off the south-western coast of West Falkland and is roughly triangular in shape. The western half of the southern coast has sheer cliffs reaching at least 70 m and the plateau above slopes gently to the north and west. In the centre of the island there is a large seasonal pool, to the west of a small inlet. The eastern promontory has two domed peaks reaching to at least 110 m with sheer southern cliffs of 30 m and very steep slopes in the north. Access by boat is difficult, except at the small north-east-facing inlet between the northern and eastern promontories, and the terrain is difficult to cross, with dense growth of Tussac above thick, soft peat and Tussac overhanging deep gulches.

Other biodiversity There are two colonies of South American Fur Seals present on Bird Island, one of about 100 individuals on the northern coast, the second on the south-western coast, comprising approximately 10,000 individuals: the largest South American Fur Seal colony within the Falklands archipelago. The island also provides a haul-out for Southern Sea Lions, although they are not known to breed there. No endemic or introduced species were recorded in 1998; only 12 native flowering plants were found with Tussac predominant.
