Population justification: The global population size has not been quantified. The species is described as 'fairly common' (Stotz et al. 1996), and it is regularly observed throughout its range (see records on eBird; eBird 2021). Based on the recorded population densities of congeners (Campephilus melanoleucus: 0.5 mature individuals/km2 and Campephilus rubricollis: 2-12 mature individuals/km2 [Santini et al. 2018]), the area of the species's mapped range (c. 125,000 km2), and precautionarily assuming that only around 10% of the range is occupied, the population is estimated to fall within the band 25,000-150,000 mature individuals.
Trend justification: The species is feared to be in slow decline due to loss of forests within the range. Deforestation rates have however been low over the past three generations (16.5 years), amounting to 7% (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species readily tolerates secondary and edge habitat (Winkler and Christie 2020). Nevertheless, it appears to require large patches of well-preserved forests nearby and reaches higher densities in forests than in secondary habitats (D. F. Cisneros-Heredia in litt. 2022). Moreover, it is locally hunted in western Ecuador (D. F. Cisneros-Heredia in litt. 2022). It is therefore precautionarily assumed that population declines exceed the rate of forest loss; they are here placed in the band 10-19% over three generations.
