Taxonomic note

Grallaria quitensis, G. alticola and G. atuensis (del Hoyo and Collar 2016) were previously lumped as G. quitensis following SACC (2005 & updates), Sibley & Monroe (1990, 1993) and Stotz et al. (1996). Original note from Illustrated Checklists: Hitherto treated as conspecific with G. quitensis and G. atuensis, but differs in its slightly smaller size with clearly smaller bill (at least 1), browner (less olive) upperparts (1), and distinctive voice (see G. atuensis for species-level difference in call), having a four-note vs three-note song with short pauses between last three notes (4) resulting in a rhythmic phrase, and reaching lower overall (vs quitensis) or maximum (vs atuensis) frequencies (1) (Boesman 2016); in playback experiments (O. Cortés pers. comm. 2016), present species and G. quitensis didn’t respond to the songs of the other members of the complex. Monotypic.

Population justification: The global population size has not been quantified, but this species is described as 'common' (Stotz et al. 1996). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 1.6% within its mapped range over the past three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Therefore, as a precautionary measure, it is tentatively suspected that this loss of cover may have led to a decline of between 1-19% in the species' population size over the same time frame.
