Population justification: The species is described as fairly common (Stotz et al. 1996, Zimmer and Isler 2020), but the global population size has not been quantified directly. Based on density estimates of a congener (M. myotherinus: 40 mature individuals/km² in Peru; Santini et al. 2018) and precautionarily assuming that only around 10% of the range is occupied, the total population may number c. 800,000 mature individuals. To account for uncertainty, the population size is therefore placed in the band 500,000-999,999 mature individuals here.

Trend justification: The population trend has not been assessed directly. Forest loss over the past ten years has been low within the range (2%; Global Forest Watch 2020). The species is strictly forest-dependent and may be susceptible to fragmentation and edge effects (A. Lees in litt. 2011), and thus population declines may be exacerbated by habitat degradation and slightly higher than forest loss. The species is therefore tentatively suspected to undergo a slow decline at up to 10% over ten years.
