It occupies a very small range on only one island when breeding and is susceptible to human impacts, introduced species and stochastic events, which could drive the species towards extinction in a very short time.

Population size: 250-999 mature individuals

Population trend: stable

Extent of occurrence (breeding/resident): 61,500,000 km²

Country endemic: yes
