Population justification: The total population on Hatuta'a was estimated at 200-250 in 1975 and 1987, 490-890 in 2002, 1,070 in 2007, <200 in 2010 and reportedly 'abundant' in 2012 (Thibault et al. 2013, C. Blanvillain in litt. 2017), with numbers potentially fluctuating because of drought (Thibault et al. 2013), although some differences may also be a result of differences in survey methods (Thibault 1988, P. Raust in litt. 2007, A. Gouni in litt. 2007, C. Blanvillain in litt. 2017). Small numbers persist on Fatu'uku, estimated at a few pairs in 2011 (Butard 2011). As the population appears to fluctuate, and it appears to be often <250 mature individuals, the population size is precautionarily placed in the range 50-249 mature individuals.

Trend justification: On Hatuta`a, the population fluctuates probably as a result of droughts, with an overall stable trend (Thibault et al. 2013). On Fatu Huku, the population was estimated at 10-100 in the 1990s, and it was thought to be similar in 2002 (Seitre and Seitre 1991, A. Gouni in litt. 2007) and in 2011, when six birds were observed on the island (Butaud 2011). Based on this information, the long-term population trend is suspected to be stable. Should the population be found to be decreasing, the species would warrant uplisting to a higher threat category.
