Current view: Data table and detailed info
Taxonomic note
Until recently treated as a lowland subspecies of A. insignis, but studies suggest that it should be afforded specific rank (Dumbacher et al. 2003, Pratt 2000). Monotypic.

Population justification: The global population size has not been quantified. The species is described as possibly fairly common, although little known (Cleere 1998), and eBird (2022) data suggest it is regularly seen, although in many instances this may refer to the same individuals. Similarly, Verbelen (2014) suggested it may be locally common. Conversely, Pratt and Beehler (2015) and Gregory (2017) described it as rare. Even if the species were to prove range-restricted or patchily distributed, the geographic spread of sites from which it is already known suggest that there is a large amount of suitable habitat in its range (G. Dutson pers. comm. 2023). Consequently the population size is unlikely to be especially small.
Trend justification: The population trend of this species has not been accurately evaluated. The only likely threat to it is habitat loss which is ongoing in New Guinea's lowlands, albeit at currently a slow rate (per Global Forest Watch 2022). The forest around Kiunga, where most observations are made, is intact with few signs of degradation; however, in neighbouring Indonesia, forest between the Fly and Digul rivers shows localised signs of novel logging tracks and ongoing degradation (Google Earth 2022). As a highly forest-dependent species (Beehler and Pratt 2016), this is likely to be having a negative impact on the species, although it is unlikely to be causing rapid declines (even acknowledging that the limits of the species' range are improperly known).
