Population justification: The global population size has not been quantified, but the species is described as generally rare, although secure and (at least formerly) fairly common in the Ok Tedi area of Papua New Guinea (del Hoyo et al. 1997). The species’ range includes large areas of rugged and well-forested terrain that remain little surveyed (I. Woxvold in litt. 2020).

Trend justification: There are almost no data on population trends. A sharp decline in records was reported from the Tabubil/Ok Tedi area, where flocks of up to 125 birds were once reported (Gregory 1995), since the severe 1997-98 El Niño drought (P. Gregory in litt. 2010). Forest loss is low within the range, occurring at a rate equivalent to c.1% over three generations (Global Forest Watch 2023, based on data from Hansen et al. [2013] and methods disclosed therein). Much of the southern slopes of the central range occupied by this species remain well-forested and the rugged terrain affords some protection against a subset of anthropogenic threats (I. Woxvold in litt. 2020). The species is precautionarily suspected to be declining slowly, owing to localised habitat degradation and the effects of severe weather.
