Population justification: The overall population of the species probably does not exceed 10,000 pairs (i.e. 20,000 mature individuals) and 30,000 individuals. It is thus placed in the band 10,000-19,999 mature individuals, and thought to number 20,000-30,000 individuals in total.
Trend justification: There are no data, however the species is thought to be declining, mainly due to nest predation by introduced predators.
