Population justification: The population size of this species has not been quantified, but given the lack of records it is unlikely to be very large. However, further surveys, particularly in potentially suitable habitat in Bolivia and Peru may be able to help conclude how abundant this species may be.

Trend justification: The species is inferred to be declining as a result of habitat loss and degradation within its range.
