Population justification: The population size of this species has not been quantified, but it is described as fairly common to locally abundant (Frith and Beehler 1998, Pratt and Beehler 2015, Beehler and Pratt 2016) and, given the extent of suitable habitat in its mapped range (19,000 km² in 2021; Global Forest Watch [2022], based on data and methods from Hansen et al. [2013]), it is considered unlikely to have a population size smaller than 10,000 mature individuals.

Trend justification: There are no data on population trends; however, the species is thought to be in slow decline, owing to ongoing (albeit slow) habitat degradation. In the three generations to 2021, forest cover loss in this species’ range was equal to 2-3% (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein). Much of this amounts to complete clearance and conversion to agriculture, such that although this species is tolerant of moderate degradation, there are likely to be some localised declines.
