White-bellied Hummingbird (Amazilia chionogaster)


French: Ariane à ventre blanc German: Weißbauchamazilie Spanish: Amazilia ventrinívea

Trochilus chionogaster


, 1846,



Formerly listed as Leucippus pallidus. Has been included in genus Leucippus, largely for reasons of morphology, behaviour and biogeography. In the past, alternatively placed in genus Chionogaster, along with A. viridicauda; sympatric with latter species in Urubamba Valley (C Peru), where hybridization not yet demonstrated. Proposed race 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.
