Justification of Red List category
Although this species may have a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the threshold for Vulnerable under the population trend criterion (>30% decline over ten years of three generations). The population size is large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Population justification
The species has a large global population estimated to be greater than 50,000 individuals (Seal et al. 1992). It is generally reported to be uncommon (Coates 1985, Beehler et al. 1986), but is locally fairly common in localities such as the Puwani River area south of Vanimo and in incompletely logged forest in the Wapoga River area (A. Mack in litt. 1999, K. D. Bishop in litt. 1999, B. Beehler in litt. 2000).
Trend justification
The species is tentatively assessed as being in decline due to habitat loss per Tracewski et al. (2016).
This species has a patchy distribution along the northern coastal lowlands of New Guinea, from the Geelvink Bay in Irian Jaya (Indonesia) to the Astrolobe Bay in Papua New Guinea. It is generally reported to be uncommon (Coates 1985, Beehler et al. 1986), but is locally fairly common in localities such as the Puwani River area south of Vanimo and in incompletely logged forest in the Wapoga River area (A. Mack in litt. 1999, K.D. Bishop in litt. 1999, B. Beehler in litt. 2000).
It favours a type of primary and tall secondary forest which has only been recorded below 150 m.
Forests throughout its range are threatened by commercial logging but the species's abundance in secondary forest suggests that it is not threatened (B. Whitney in litt. 2000).
