Justification of Red List category
Once among the rarest birds of the world, this species has been brought back from the brink of extinction. It has been downlisted to Vulnerable as the population has increased in recent years owing to intensive conservation efforts with no evidence of a continuing decline for the last five years. However, it still has a very small population and range and remains threatened by chance events such as cyclones and other stochastic factors that could drive it to qualify as Critically Endangered or even Extinct in a short time period. The survival of the species remains dependent on a continuation of intensive conservation efforts.
