Population justification: It inhabits areas which are very rarely visited but is likely to prove to be locally common as with other New Guinea congeners (Coates 1985, Beehler et al. 1986). It was recorded as common in the Bewani and Torricelli (J. Diamond in litt. 1987, Collar et al. 1994) but this was based on seven specimens taken in 1966 (Diamond 1969) and it has not been recorded (or searched for) there subsequently. In the Cyclops, it is known from four specimens (Diamond 1969) and was not found during fieldwork in 1992 (K. D. Bishop in litt. 1996). It was common to uncommon from 1,198–1,680 m in the Foja Mountains in 2005-2009 (Beehler et al. 2012), confirming provisional records there in 1979 and 1981 (Diamond 1985).

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
