Population justification: Encounter rates of this species were recorded at 30-90 birds per km2 by Buckingham et al. (1990), which would roughly equate to 20-60 mature individuals per km2, and subsequent field work on the island appears consistent with these densities (Danielsen et al. 2010, G. Dutson in litt. 2016). Therefore, conservatively assuming only a proportion of its range is occupied, the population size of this species would fall in the range 10,000-30,000 mature individuals. However, this may be an underestimate of the overall population size (per G. Dutson in litt. 2016).
Trend justification: The population is suspected to be stable overall in the absence of evidence for any declines or substantial threats, particularly as this species is relatively tolerant of degraded habitats (Buckingham et al. 1990; G. Dutson in litt. 2016).
