Population justification: The population size is difficult to quantify, with descriptions ranging from very common (Juniper and Parr 1998, Forshaw 2006), to patchily distributed and very uncommon (J. Gilardi in litt. 2010). The species however seems to be difficult to detect and may in future be found more widespread (Collar and Boesman 2020). Preliminarily, the population size is here placed in the band 2,500-9,999 mature individuals, though this requires confirmation.

Trend justification: The population trend has not been assessed directly. The only threat known to the species is habitat loss. Forest loss however has been low within the range over the past ten years (2%; Global Forest Watch 2020). Due to the species’s apparent restriction to riparian forests and forests with a relatively open canopy, rates of population decline may be exacerbated by additional effect of forest degradation and larger than rates of forest loss alone. Nevertheless, population declines are unlikely to exceed 10% over ten years.
