Justification of Red List category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996).

Trend justification
The population trend has not been investigated, but due to its dependence on forests and low tolerance of converted habitats, declines are suspected on the basis of habitat loss and degradation (Züchner and Boesman 2020). Tree cover within the range is lost at a rate of 3% over ten years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Population declines are likely exacerbated by additional habitat degradation, so that they are here tentatively placed in the band 1-19% over ten years.

Campylopterus villaviscensio occurs on the east slope of the Andes from southern Colombia through Ecuador to northern Peru.

It occurs in montane humid and elfin forest (Züchner and Boesman 2020). Its ecology is not well known.

Locally, forests within the range are under threat from conversion for agriculture and cattle pasture, mining and logging (Dinerstein et al. 1995, Züchner and Boesman 2020).

Conservation Actions Underway
CITES Appendix II. It is listed as Near Threatened at the national levels in Peru and Ecuador (SERFOR 2018, Freile et al. 2019).

Conservation Actions Proposed
Search for the species in potentially suitable habitat at new sites. Obtain an accurate estimate of its population size and trends. Study its ecology and its ability to persist in degraded and fragmented habitats. Monitor the population trend. Effectively protect and manage core areas of remaining habitat.
