Justification of Red List category
This species has a very small breeding range, and is only known to breed on four tiny islets around Rapa, French Polynesia, but potentially also on the main island. The population is undergoing a drastic decline, presumably as a result of depredation by introduced mammals. Therefore, this newly-split species is listed as Critically Endangered.

Population size: 50-249 mature individuals

Population trend: decreasing

Extent of occurrence (breeding/resident): 126,000 km²

Country endemic: yes
