Population justification: The total population is estimated to lie within the band 20,000-30,000 individuals, equivalent to c.13,200-20,000 mature individuals, based on recent survey data estimating density and area of occupancy (Trainor 2002).

Trend justification: Thought to be declining slowly. Between 2001 and 2020, forest cover on Damar reduced by 2.4%, equivalent to a loss of c.1.1% over three generations (Global Forest Watch 2021, using data from Hansen et al. 2013 and methods disclosed therein). However. these data are thought to underestimate the threat of ongoing habitat degradation and population decline with much growing of crops below the canopy, creating habitat apparently unsuitable for the species, as undetected by remote sensing data (J. Eaton in litt. 2022). There is additional evidence of population declines in response to the expansion of crop growing and infrastructure projects. For example, in 2016, the clearance of forest/understorey to build a new road to connect the main villages removed at least six flycatcher territories that were previously occupied; if the road has been expanded or completed since, a larger number of territories may have disappeared (J. Eaton in litt. 2022).
