Population justification:
The population in Ecuador is estimated at 2,500 individuals (Freile et al. 2011). The population in Peru is suspected to number 2,500-10,000 individuals (SERFOR 2018). Combining national population sizes, it is precautionarily inferred that the global population may number 5,000-12,500 individuals, roughly converted to 3,000-8,999 mature individuals. This however requires confirmation.
Trend justification: This species is in decline as a consequence of the loss and fragmentation of its habitat. Tree cover loss within the species range equates to <2% over ten years (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). And although the species can inhabit stunted forest on poor, sandy soils that do not support agriculture or cattle ranching, it is not considered to inhabit completely deforested areas (Heynen et al. 2020). For these reasons, the species is suspected to be undergoing a rate of decline equating 1-9% over three generations.
