Population justification: It is restricted to altitudes of 1,200-1,450 m (rarely to 990 m). The numbers of bowers found per km² documented by Frith and Frith (2004) for other species in the genus are 15/50 km² and 24/48 km² (with the maximum from 23 studies of all bowerbirds being 36/2.5 km²). It is reported as common at Keki Lodge but rare between Wanuma and Mt Mengam (Beehler and Pratt 2016). It seems likely that the total population numbers fewer than 10,000 mature individuals (G. Dutson in litt. 2009), and so it is placed in the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.

Trend justification: Forest in the Adalbert Mountains is largely inaccessible and unlikely to be under significant threat in the near future, the species remains common in its favoured habitat, and there is no evidence of a decline (B. Beehler & K. Vang in litt. 2008). Thus the species is tentatively listed as being stable. However satellite imagery shows an ongoing slow loss of forest across the Adelberts.
