Cavalos island is the second most important breeding site of birds in West Africa. There are about 19,000 nests of terns and other species. The island is small and deserted; you can go around it across splendid beaches within only two hours. The island is inhabited not only by terns but also by an exceptionally big number of African fish eagles. Cavalos island stands out against other islands of the Bijagos archipelago due to extensive areas resembling moors.
