Population justification: The population size of this species has not been quantified, but given the paucity of records and small range it is unlikely to be very large. However, further surveys, particularly in potentially suitable habitat in Bolivia and Peru, may help conclude how abundant this species may be.
Trend justification: The population trend has not been investigated. Within its known range, deforestation is ongoing and extensive (Global Forest Watch 2022). Over the last ten years, 15% of tree cover has been lost within the range; since 2017 this has been increasing to a rate equivalent to 19% over ten years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The species is however not dependent on mature forest, but occurs in a variety of secondary, edge and successional habitats (Zimmer et al. 2013), and therefore population declines may not be as steep as the rate of tree cover loss suggests. Nevertheless, the population is likely affected by the extensive and large-scale clearance of shrubby and herbaceous habitat, which is ongoing throughout large parts of the range. Thus, the population is suspected to be in decline, though the exact rate is not known.
