Taxonomic note
A distinctive species within the so-called “croaking group” (see R. toco). Although plumage characters suggest possible sister relationship to R. sulfuratus, genetic data indicate that present species is sister to R. vitellinus (Patané et al. 2009). Long considered to be a subspecies of R. ambiguus, but differs significantly in voice; size smaller, bill shorter with more yellow; sympatric with R. a. swainsonii. Monotypic.

Population justification: The global population size has not been quantified, but the species is described as uncommon or locally common in Ecuador (del Hoyo et al. 2002). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 4% 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.
