Taxonomic note
Previously listed as Amazilia chionogaster (del Hoyo and Collar 2014), and before that as Leucippus pallidus, 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 been included in genus Leucippus, largely for reasons of morphology, behaviour and biogeography. In the past, alternatively placed in genus Chionogaster, along with E. viridicauda; sympatric with latter species in Urubamba Valley (C Peru), where hybridization not yet demonstrated. Proposed subspecies longirostris, described from N Argentina (Salta), doubtfully distinct from hypoleuca; differences in morphometry (e.g. bill length) and plumage characters of subpopulation concerned appear not to be significant. Described form A. nigrirostris generally considered a synonym of present species, but may be better considered unidentifiable. Two subspecies 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 4.9% 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.
