Population justification: The population size has not been estimated but this species is described as uncommon throughout its range (Dutson 2011, Callaghan et al. 2019).
Trend justification:
The population is inferred to be declining owing to forest loss and degradation. Malaita has experienced moderate levels of logging and a slow rate of deforestation (Katovai et al. 2015), and remote sensing data (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein) indicate that in the ten years to 2020, forest loss in this species' range has been equivalent to 3-5%. This may accelerate slightly (to an equivalent rate of 4-6%) in the future based on losses 2015-2020. The species is described as rare in heavily degraded forest (Dutson 2011) such that the population is inferred to be declining and these losses are not expected to slow or cease, with extensive areas of Malaita under logging concessions (Katovai et al. 2015).
