The Îles Nuageuses (Cloudy Islands in English) comprise a group of small islands that are part of the subantarctic Kerguelen archipelago, a French territory in the southern Indian Ocean. They are important as a breeding site for seabirds, especially penguins and albatrosses, and for fur seals.
The group is located in the northwestern area of the archipelago. It lies about 15 kilometres (9.3 miles) north-west, across the Jean-Baptiste Charcot Channel, from the tip of the Loranchet Peninsula, the northernmost extension of Grande Terre, the principal island of the Kerguelens. The islands are of volcanic origin.
The main islands of the Nuageuses are Île de Croÿ, Île du Roland, Île d’Après and the Îles Ternay, with the small Île Clugny some 12 kilometres (7.5 miles) to the south of the others. Far to the north lies the Îlot du Rendez-vous. The highest point in the group is just over 500 m above sea level and the coastlines are mainly sheer cliffs.
The îles Nuageuses were first sighted during Yves Joseph de Kerguelen de Trémarec second expedition in 1773. They were so named after the frequently mist-covered tops of their cliffs and were referred to as Cloudy Isles by James Cook in 1776.
Important Bird Area
The Îles Nuageuses, including Île Clugny, have been identified as a 240 km2 Important Bird Area (IBA) by BirdLife International. At least 25 bird species breed on the islands. Penguins include 7500 pairs of gentoos, 35,000 pairs of northern rockhoppers and up to 50,000 pairs of macaronis. Of albatrosses, there are 1800 pairs of black-browed, 7800 pairs of grey-headed, 50 pairs of Indian yellow-nosed, about five pairs of wandering and some light-mantled albatrosses. Other birds breeding on the islands include Antarctic prions, Kerguelen, white-chinned, Wilson's storm and common diving petrels, and black-faced sheathbills. There are also small numbers of northern giant petrels, Kerguelen shags, Eaton's pintails and Kerguelen terns.
