Justification of Red List category
This species has a large population which is currently thought to be stable, it is confined to just three islands all in close proximity and as such it is susceptible to the effects of human activities or stochastic events. However there are currently no obvious threats that could result in the species qualifying for Critically Endangered in a short time period. The species is therefore classified as Near Threatened as it almost meets the requirements for listing as threatened under criterion D2.
1700000 mature individuals
Distribution size (breeding/resident):
Land-mass type - oceanic island - Oceanic islands are islands or island groups that are <200,000 sq km in size and separated from other land masses by >200 m sea depth. Generally Oceanic islands are islands or island groups that are <200,000 sq km in size and separated from other land masses by >200 m sea depth. Generally they have never been connected to a continental area by a land-ridge, and are volcanic in origin.
