Taxonomic note
Previously split as Conirostrum cinereum and C. fraseri (del Hoyo and Collar 2016), and before that lumped as C. cinereum following SACC (2005 and updates); Sibley and Monroe (1990, 1993); Stotz et al. (1996). The split of C. fraseri was based on differences in plumage and structure (del Hoyo and Collar 2016) but further examination of specimens has suggested the differences are not as pronounced as originally thought and possibly clinal, so fraseri returned to subspecies level. Lower-elevation subspecies littorale moderately distinct from nominate, being paler overall (1), rather smaller (effect size for wing –2.52, score 2), arguably with different habitat requirements (ns yet) and apparently with a daytime song with a much narrower frequency range (typically 3–5 kHz vs 7–9 kHz) and higher minimum frequency (typically >5 kHz vs >2 kHz) (Boesman 2016); thus very close to species rank, but further evidence on voice needed to confirm distinctions and to score them robustly. Three subspecies recognized.

Population justification: The global population size has not been quantified, but this species is described as 'common' (Stotz et al. 1996). It is widespread in its range (per eBird 2023) and therefore the population is unlikely to be small.

Trend justification: The species occurs in a variety of habitat, including in heavily modified and disturbed areas (Chavez 2020). Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.
