Taxonomic note
Previously listed as Amazilia fimbriata (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 previously been placed in genus Polyerata or Agyrtria. Closely related to C. lactea. Subspecies fluviatilis, nigricauda and tephrocephala were all previously treated elsewhere as distinct species. Several proposed subspecies are invalid owing to similar morphology and range overlap with adjacent forms: obscuricauda has proved to be identical to elegantissima; maculicaudus and alia are inseparable from nominate. In Venezuela, the very local form described as Amazilia distans (known only from Táchira) is now thought probably of hybrid origin, present species x Chlorestes cyanus, although sometimes recognized as valid (Restall et al. 2006). Has been suggested that proposed species Amazilia cyaneotincta, known only from two skins of uncertain origin, is an aberrant form of present species, but this seems unlikely; in plumage pattern it is more similar to Polyerata amabilis. Seven subspecies currently recognized.

Population justification: The global population size has not been quantified, but this species is described as 'common' (Stotz et al. 1996). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 6.4% within its mapped range over the past 10 years (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.
