Short-tailed Emerald Chlorostilbon poortmani


Taxonomic note
Chlorostilbon poortmani and C. alice were previously lumped under C. poortmani (del Hoyo and Collar 2014) having previously been split following Sibley and Monroe (1990, 1993). Now the two taxa are split again (see under C. alice). Closely related to C. stenurus. Subspecies euchloris has sometimes been considered a separate species, owing mainly to suggestion of possible overlap in range, but poorly known. Described forms inexpectatus and auratus, known from single specimens from “Bogotá” and “Peru” (Peru not part of range), respectively, are apparently aberrant individuals of present species. Two subspecies recognized.

Population justification: The global population size has not been quantified, but this species is described as common to fairly common (Bündgen et al. 2020).

Trend justification: Vast areas of pristine forests remain across the species' range (Global Forest Watch 2022). Although the species is forest-dependent, it readily accepts man-made habitats such as plantations, parks and gardens where stands of shrubs and trees are found (Bündgen et al. 2020). Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.
