Cape Verde has less fauna than just about anywhere in Africa. Birdlife is a little richer (around 75 species), and includes a good number of endemics (38 species). The frigate bird and the extremely rare razo lark are much sought after by twitchers. The grey-headed kingfisher is more common though with its strident call.
Divers can see a good range of fish, including tropical species such as parrot fish and angelfish, groupers, barracudas, moray eels and, with luck, manta rays, sharks (including the nurse, tiger and lemon) and marine turtles. Five species of turtles visit the islands on their way across the Atlantic. Nesting takes place throughout the year, but in particular from May to October.
