Population justification: The population size has not been quantified. Other Phaethornis species in Peru were found to occur at densities of 1 individual/km² (P. stuarti) to 4 individuals/km² (P. hispidus; Santini et al. 2018). Assuming that this species occurs at a similar density, and that 25% of forests within the range are occupied to account for its disjunct and localised distribution (i.e., 20,000-21,500 km²; Global Forest Watch 2022), the global population may number 20,000-86,000 mature individuals. This roughly equates to 13,000-57,000 mature individuals.

Trend justification: The population trend has not been investigated, but declines are suspected on the basis of habitat loss and degradation. Tree cover loss within the range has been accelerating in recent years to a rate of 7% over ten years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The species is strictly dependent on mature forests and has a low tolerance of secondary habitats (Schulenberg 2020); therefore, population declines may be steeper than the rate of tree cover loss suggests. Tentatively, population declines are here placed in the band 10-19% over ten years.
