Population justification: The last surveys estimated 1,763-2,987 individuals (Ziembicki and Raust 2004) and 2,094 individuals on Ua Huka (T. Doukas in litt. 2010), although these may have overestimated the population as the species is much less common in the uninhabited part of the island (Blanvillain 2012), and so the total population is placed in the band 1,000-2,499 individuals.

Trend justification: On Ua Huka the population was c.200-250 pairs in the early 1970s, c.1,300 individuals in 1991 (Holyoak and Thibault 1984, Thibault 1988, Kuehler et al. 1997), 1,763-2,987 individuals in 2004 (Ziembicki and Raust 2004) and 2,094 individuals in 2009 (T. Doukas in litt. 2010). The population is therefore currently estimated to be stable (P. Roust in litt. 2017; T. Doukas in litt. 2017).
