Justification of Red List category
This species is listed as Critically Endangered because it has an extremely small range, restricted to one island, where the population exhibits marked population fluctuations, probably owing to climatic events. The accidental introduction of mammalian predators, non-native pest plants, insects or an avian disease, or a stochastic event such as a hurricane could rapidly bring about its extinction.

Population size: 2400-3600 mature individuals

Population trend: stable

Extent of occurrence (breeding/resident): 2 km²

Country endemic: yes
