Population justification: A survey of Aketajawe Lolobata National Park in 2012 resulted in a population estimate of 2,900 individuals (Bashari 2012) for an area totalling 1,673 km², roughly equating to 1.7 individuals/km². Assuming 10% of the overall area of mapped range is suitable habitat for the species, this indicates an approximate total population of 3,100 individuals, roughly equating to 2,100 mature individuals. To account for uncertainty, population size is placed here in the band of 2,500-9,999 individuals, roughly converted to 1,500-7,000 mature individuals.

Trend justification: The population was suspected to be in decline owing to on-going habitat destruction (Ferguson-Lees and Christie 2001). Vetter (2009) used remote sensing techniques to track the rate and spatial pattern of forest loss in the North Maluku Endemic Bird Area between 1990 and 2003, and projected rates of deforestation over three generations for restricted range bird species found in this region. This study estimated the rate of forest loss within the geographic and elevation range of the species to be c.20% between 1990 and 2003, and projected the loss of c.36% of forest in its range over three generations. However, it may be tolerant of some habitat modification, and is found at higher elevations, where forest is expected to be comparatively more secure, perhaps buffering its population against the impacts of projected forest loss throughout its geographic range.  Recent studies have further shown that projected forest loss may have been overestimated, with past rates to have been negligible at approximately 4-7% (Tracewski et al. 2016, Global Forest Watch 2020) over a three-generation period (15.3 years; see Bird et al. 2020). Assuming forest loss has continued at the same rate, it is suspected that the population may therefore be undergoing only a slow decline. However, the species may be affected by additional factors in the future, such as forest fires, accelerating declines over forest loss alone. Nevertheless, rates of decline are unlikely to have exceeded 10% and is suspected to continue at similar rates in the future.
