Taxonomy

Taxonomic note

Grallaria quitensis, G. alticola and G. atuensis (del Hoyo and Collar 2016) were previously lumped as G. quitensis following SACC (2005 and updates), Sibley and Monroe (1990, 1993) and Stotz et al. (1996). Original note from Illustrated Checklists: Hitherto treated as conspecific with G. quitensis and G. alticola, but differs from both in its darker overall coloration (1), more distinct white mottling below (1), and very different call-note (a long, very burry start followed by an underslurred whistle vs a modulated start followed by a downslurred whistle in quitensis and a smooth downslurred whistle in alticola), with smaller frequency range (at least 2), lower maximum frequency (ns1) and longer note length (3) (Boesman 2016). 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 0.8% within its mapped range over the past three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Its population trend is therefore considered stable.
