Population justification: The global population size has not been quantified, but the species is described as relatively uncommon and little known (del Hoyo et al. 2006, Dutson 2011).

Trend justification: This species is thought to be declining as a result of ongoing forest loss on Makira. 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.3-4%. The species is described as restricted to old-growth closed-canopy forest (Dutson 2011, Dutson in litt. 2016) and recent observations of the species are only from unlogged forest (Mittermeier et al. 2018) such that it is inferred to be declining as a result of forest loss, although the rate has not been quantified.
