Justification of Red List category
This species is classified as Vulnerable as it has a very small area of occupancy, with the vast majority of the global population restricted to one tiny island where invasion by feral cats was a concern. Following the cat eradication on the adjacent main island of Ascension, this risk has now been substantially reduced. Censusing the population and ascertaining trends is particularly problematic. There is currently no evidence that this species qualifies for for a different threat category.
