White-chested Emerald Chrysuronia brevirostris



Taxonomy

Taxonomic note
Previously listed as Amazilia brevirostris (del Hoyo and Collar 2014), but moved to current genus following a recent overhaul of all genera by NACC, based on McGuire et al. (2014), Stiles et al. (2017a, b) and others. Has sometimes been placed in genus Agyrtria. Species name has normally been given as chionopectus, as name brevirostris was believed to refer to C. versicolor with an erroneous type locality. With rectification of name and consequent revised type locality, subspecies formerly listed as whitelyi becomes nominate, with whitelyi as a synonym. Three subspecies recognized.

Population justification: The global population size has not been quantified, but this species is described as overall common, but varying in abundance across the range (Stotz et al. 1996, Weller and Boesman 2020).

Trend justification:

The population trend has not been investigated. Tree cover loss within the range is very low (2% over ten years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species occurs in a variety of habitats, including forests, edge and secondary forest, scrub, savanna and cultivated land (Weller and Boesman 2020); consequently, the current rate of tree cover loss may not be affecting the population. Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.
