Justification of Red List category
This species is classified as Critically Endangered because, although it has increased, it still has only a small population, largely derived from captive-reared individuals. The annual release of substantial numbers of captive-reared birds, in combination with predator control, has almost certainly prevented it from becoming Extinct in the Wild, and the species's long-term survival remains dependent upon this intensive conservation management.

Population size: 1-49 mature individuals

Population trend: increasing

Extent of occurrence (breeding/resident): 3,300 km2

Country endemic: yes

Land-mass type - oceanic island
