Population justification: Estimations of this species' population size have slightly varied, but there remains a reasonable probability it numbers fewer than 250 mature individuals. In 2000, the population was estimated 80-125 pairs (i.e. 160-250 mature individuals) based on a density of 4-5 pairs/10 ha in Pisonia forest (Thibault and Meyer 2001). In 2019, a more thorough exercise of territory mapping all accessible parts of the islands identified 302 birds (including young birds) and 109 pairs, with 330-500 birds estimated across the entire island (Blanvillain et al. 2019). The population is therefore considered to number 220-330 mature individuals.
Trend justification: The population appeared healthy in 2019 (Blanvillain et al. 2019) as in 2006 (P. Raust in litt. 2007) and is estimated to be stable or increasing due to the extension of the Pisonia forest (C. Blanvillain in litt. 2020).
