This 200-km² island (also known as Nosy Boraha) off the north-east coast of Madagascar is a Secondary Area (see map, p. 332) on the basis of its one endemic (extinct) species, Snail-eating Coua Coua delalandei, which was last recorded in 1834. Investigations and interviews with local people on the adjacent mainland have failed to indicate that the species ever occurred elsewhere, and it is assumed that deforestation on the island was the principal cause of the species' demise, with hunting and predation by introduced rats Rattus rattus also contributing (Goodman 1993).
