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, but censusing the population and ascertaining trends is particularly problematic.

Population size: 17000-21000 mature individuals

Population trend: stable

Extent of occurrence (breeding/resident): 2,620,000 km²

Country endemic: yes

Attributes
