Green-and-white Hummingbird Elliotomyia viridicauda

Current view: Data table and detailed info

Taxonomy

Taxonomic note
Previously listed as Amazilia viridicauda (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 been included in genus Leucippus, largely for reasons of morphology, behaviour and biogeography. In the past, alternatively placed in genus Chionogaster, along with E. chionogaster; sympatric with that species in Urubamba Valley (C Peru), where hybridization not yet demonstrated. Monotypic.

Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996). This species is considered to have a high dependency on forest habitat, and tree cover is estimated to have declined by 3.7% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). It is therefore tentatively suspected that this rate of cover loss may have led to a decline of between 1-19% in the species' population size over the same time frame, with a best estimate of reduction being less than 5%.
