Population justification: The population is estimated to number 250-999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.
Trend justification: Although forest habitats on Kofiau are experiencing limited clearance and degradation through slash-and-burn agriculture and selective logging, this species persists in traditional gardens, secondary forest and selectively logged forest (Diamond et al. 2009; K. D. Bishop in litt. 2013), indicating some tolerance of habitat modification. Furthermore, a visit to the island in December 2011 found no evidence of large-scale development, increased clearance or habitat conversion (B. Beehler in litt. 2012). On this basis the species is suspected to be stable.
