Justification of Red List category
This species has a small population within a very small range: almost certainly only now occurring on one very small island. Although it may currently be increasing there owing to a cessation of mining activities and hunting, it could decline rapidly in the near future owing to habitat destruction, or if Swamp Harrier Circus approximans colonises the island. Recent surveys suggest that the population size is larger than previously thought, but the imminent threat of a resumption of mining activities on Makatea means that future continuing declines in area of occupancy, area/quality of habitat and population size are likely. Therefore, the species is listed as Endangered, though if these future threats do not materialise the species will warrant downlisting.
