Ilhéus do Rombo


The Ilhéus do Rombo, also known as the Ilhéus Secos, are a group of small, uninhabited islands in the Cape Verde archipelago, lying off the coast of north-west Africa in the Atlantic Ocean. The islets form an integral nature reserve. They are sited on a volcanic seamount north of Brava and west of Fogo. The two major islets of the chain are Ilhéu Grande and Ilhéu de Cima. Administratively they are part of the municipality of Brava. They can be seen from Brava and, sometimes, from Fogo.

Description

The larger islets have some sparse grassland. Ilhéu Grande is on the west side of the group. It has a length of about from south-west to north-east and a width of, with a small bay in the north-west. Ilhéu de Cima, on the east of the group, is about long and ; wide, with a small bay in its south-east. Some smaller unvegetated islets and rocks, including the Ilhéu do Rei, Ilhéu Sapado and Ilhéu Luiz Carneiro, lie between them.

Fauna

Ilhéu de Cima is famous for its seabird colonies. Ilhéu Grande, which has been used by goat farmers and whalers in the past, does not currently support breeding seabirds, though large colonies must have existed formerly as the island has thick layers of guano. The island group has been identified as an Important Bird Area by BirdLife International because it supports seabird colonies as well as peregrine falcons and Iago sparrows. Birds include the Frigate bird numbering around 1,000 in 1989, the Boyd's shearwater, Oceanodroma castro, Bulwer's petrel, the brown booby and Phaethon aethereus. Also there is a subspecies of the Peregrine falcon named madens, discovered in the mid-1960s with only 15 to 20 pairs.
Sea turtles have been reported to nest occasionally on the small, sandy beaches of Ilhéu de Cima. Other marine fauna also dominates underwater surrounding the islets. Other fauna includes the gecko species Tarentola protogigas.
