Justification of Red List category
The population size, structure and trends of this species are very poorly known. Total numbers are certainly very low and probably declining, and there may well be movement of birds between populations on different islands. It is unlikely that the total population exceeds 500 birds, with fewer than 250 mature individuals in each subpopulation, and is in decline. The species is therefore listed as Endangered. Dedicated surveys are needed urgently, and may reveal that the species warrants uplisting to Critically Endangered on the basis of an even smaller population.

Population size: 250-999

Population trend: Decreasing
