German: Weißbauchamazilie
Spanish: Colibrí Ventriníveo
Taxonomy: Trochilus chionogaster Tschudi, 1845, Peru.
Has been included by most modern taxonomists in genus Amazilia, but separation from Leucippus cannot be maintained, for reasons of morphology, behaviour and biogeography. In past, alternatively placed in genus Chionogaster, along with L. viridicauda; sympatric with that species in Urubamba Valley (C Peru), but hybridization not yet demonstrated. Formerly listed as L. pallidus. Proposed race longirostris, described from Salta, Argentina, doubtfully distinct from hypoleucus; differences in morphometry (e.g. bill length) and plumage characters of .. View all taxonomy...
Has been included by most modern taxonomists in genus Amazilia, but separation from Leucippus cannot be maintained, for reasons of morphology, behaviour and biogeography. In past, alternatively placed in genus Chionogaster, along with L. viridicauda; sympatric with that species in Urubamba Valley (C Peru), but hybridization not yet demonstrated. Formerly listed as L. pallidus. Proposed race longirostris, described from Salta, Argentina, doubtfully distinct from hypoleucus; differences in morphometry (e.g. bill length) and plumage characters of subpopulation concerned appear not to be significant. “L. nigrirostris” generally considered synonym of present species, though may be better considered unidentifiable. Two subspecies recognized.
Subspecies and Distribution:
- chionogaster (Tschudi, 1844) - N & C Peru.
- hypoleucus (Gould, 1846) - SE Peru, Bolivia and NW Argentina; possibly also EC Brazil (Mato Grosso) and Paraguay.
