Passage Islands

The largest of the group is Second Passage Island which is 9 km (5.6 mi) long from east to west and up to 2 km (1.2 mi) wide. Much of the coastline is characterised by cliffs up to 30 metres (98 ft) high. The highest point is 75 metres (246 ft) Sixtus Hill. Past overgrazing has caused erosion and reduced the cover of tussac. There are several ponds, one of which provides feeding habitat for waders and waterfowl. Third and Fourth Passage Islands are 800 m apart and low lying, rising to about 30 metres (98 ft). They were only briefly stocked with cattle in the 1960s and have good tussac coverage.^[1]

The Passage Islands group has been identified by BirdLife International as an Important Bird Area (IBA). Birds for which the site is of conservation significance include Falkland steamer ducks, gentoo penguins (300 breeding pairs), southern rockhopper penguins (145 pairs), southern giant petrels, striated caracaras, white-bridled finches, blackish cinclodes and Cobb's wrens.^[1]
