Justification of Red List category
This species qualifies as Vulnerable because it has a small breeding range and a small number of breeding locations, and may be declining overall owing to predation by introduced mammals. Although the Australian breeding population is currently increasing through conservation action, the New Caledonian population is undoubtedly in decline.
2000-14000 mature individuals
