Justification of Red List category
This species is restricted to one island and has undergone a severe population decline in recent decades as a result of forest loss, invasive species and severe hurricanes in both 2016 and 2019. Any remaining population is likely extremely small and continuing to decline. For these reasons, the species is listed as Critically Endangered.

Population size: 1-49 mature individuals

Population trend: decreasing

Extent of occurrence (breeding/resident): 80 km²

Country endemic: yes
