Taxonomic note
Previously recognised subspecies calcirupicola and diamantinensis (del Hoyo & Collar 2014) now regarded as full species, which see. Subspecies obscurus might also be better regarded as a full species (Lopes et al. 2017). C. l. largipennis differs from C. l. obscurus by its longer ‘LTTs’ (light tail-tips) (effect size 7.22 for male LTT1 vs the slightly longer values under ‘aequatorialis’; score 3); white vs greyish-white tail-tips (1); dark grey vs blackish-blue rest of outer rectrices (1); distinctly different call, higher-pitched and lacking the rolling ‘r’ tone in obscurus (at least 2). Subspecies aequatorialis regarded as a synonym of obscurus. Two subspecies recognized.

Population justification: The global population size has not been estimated directly, but this species is described as uncommon to locally very common (Abrahamczyk and Kessler 2010). Recorded population densities include 2 individuals per km² in Peru (Terborgh et al. 1990), 7.2-13.9 individuals per km² in French Guiana (Thiollay 1986), and 18.4 individuals per km² in primary forest and 7.2-8.8 individuals per km² in logged forest, both also in French Guiana (Thiollay 1992). Based on the minimum and first quartile of these densities, the estimated area of forest with at least 30% canopy cover within the range in 2010 (611,000,000 km²; Global Forest Watch 2021), and assuming forest to be 10-40% occupied, the population size is tentatively suspected to fall within the range 4,000,000 - 20,000,000 individuals, roughly equating to 3,000,000 - 13,000,000 mature individuals. Given that the species has multiple supspecies, it can be deduced that there are multiple subpopulations.

Trend justification:

Remote sensing data on tree cover loss indicates that approximately 4% of tree cover with at least 30% canopy cover was lost from within the species's range over ten years to 2020 (Global Forest Watch 2021). Based on the rate of tree cover loss over the period 2016-2020 (Global Forest Watch 2021), it is projected that 6% tree cover may be lost from the species's range over the next decade. Although the species favours forest edges, it is assumed that deforestation will eventually impact on the species's population size, and so it is inferred to be declining slowly, at a rate suspected to be less than 10% per decade.
