African Banks : ウィキペディア英語版 | African Banks
The African Banks are the uninhabited northernmost islands of the Amirantes group, of the Outer Islands of the Republic of Seychelles, in the western Indian Ocean. ==Description== The African Banks lie about 220 km west of the main Seychelles island of Mahé. Formerly small two islands, by 1976 South Island had eroded to a small sandstone ridge exposed only at low tide. North Island is small and flat with an area of 30 ha. It has a derelict automatic lighthouse and is occasionally visited by tourists in charter yachts. It is almost treeless, being vegetated by grasses and low shrubland. It is significant as a nesting site for terns, the colonies of which are subject to frequent exploitation and disturbance by poachers.〔 The islands, with an associated tract of coastal marine habitat, form a 750 ha Important Bird Area (IBA), identified as such by BirdLife International because it supports populations of black-naped (10 breeding pairs) and sooty terns (5000–10,000 pairs), and brown noddies (2000–5900 pairs). green and hawksbill sea turtles nest there.
