Geography

Bird Island is located 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.
