Population justification: Rare and local (Athanas and Greenfield 2016). This species occupies a similar range to El Oro Parakeet (Pyrrhura orcesi), the population of which has been estimated at 250 to 1,000 individuals in 2006. The Ecuadorian Tapaculo is more patchily distributed within this range. Analyses of density and habitat suitability covering 113 territories in the southern part of the species’s range suggest a total population of 3,220 mature individuals (range 1,894-4,598) (Hermes et al. 2018).

Trend justification: The population is considered to be in decline as habitat within the species's restricted range is lost and deteriorates. Deforestation at the species's stronghold in El Oro has been severe and it has become hard to find in the Buenaventura reserve, where it was reportedly common 12 years ago (L. Navarete in litt. 2006). In addition, upslope movement owing to climate change appears to be ongoing (Hermes et al. 2018). This upslope movement is projected to lead to a continued shrinkage of the distributional size (at least 25% shrinkage until 2050 under the RCP4.5 climate change scenario), with available habitat shrinking by at least 33% (M. Schaefer in litt. 2016).
