Population justification: The global population is suspected to number 50,000-499,999 mature individuals (Partners in Flight 2022). The species is described as 'fairly common' (Stotz et al. 1996).

Trend justification: The population trend has not been investigated. Tree cover within the range is lost at a rate of 7% over three generations (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species is restricted to dense, tangled undergrowth of humid forests (Zimmer and Isler 2020); therefore, population declines may be exacerbated by habitat degradation and exceed the rate of tree cover loss. Tentatively, declines are here placed in the band 10-19% over three generations.
