Justification of Red List category
This species has a very restricted range with a small population that is suspected to be declining as a result of ongoing declines in the area and quality of its habitat. It is therefore assessed as Near Threatened.

Population justification
The population is described as fairly uncommon (Dutson 2011), but is poorly-known. 18 individuals were recorded in 22 hours of observations in secondary forest with varying levels of degradation (G. Dutson in litt. 2016). Given the small range (Djaul is 165 km²) and noted preference for old-growth habitat, which is being lost at a significant rate and is now limited in extent, the population is precautionarily suspected to be in the band 2,500-9,999 mature individuals.

Trend justification
This population is suspected to be in decline owing to ongoing habitat loss and degradation (Gregory et al. 2020). Remote sensing data (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein) indicate that in the ten years to 2021, forest loss in this species' range has been equivalent to c.2-3%, and this is thought to be continuing. Steeper declines in 2021 suggest that this could accelerate to a rate equivalent to c.4-5% over ten years in the future. Population declines are suspected to be roughly equivalent to the rate of tree cover loss. The current rate of population decline is therefore placed in the range 1-9% over ten years.

This species is endemic to Djaul Island in Papua New Guinea.

The species occurs in primary and tall secondary evergreen forest from lowlands into the hills on Djaul (Coates 1990, G. Dutson in litt. 1999, Hornbuckle 1999). It appears to be more common in old-growth forest including mature secondary, and less common in secondary regrowth and gardens (G. Dutson in litt. 2016).

There remains a reasonable percentage of forest on Djaul, however there is ongoing forest loss within its range (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein) from which a slow but ongoing population decline is suspected, given that this species seems relatively intolerant of degraded forest (G. Dutson in litt. 2016).

Conservation Actions Underway
None is known.

Conservation Actions Proposed
Conduct research to determine population size. Conduct surveys and interview local villagers to determine population trends. Determine habitat requirements. Monitor numbers at sites across the island. Publicise this species' range and status through public awareness discussions.
