The white-bellied hummingbird (Elliotomyia chionogaster) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Argentina, Bolivia, Brazil, and Peru. The white-bellied hummingbird has at various times been placed in genera Leucippus and Elliotia, and until 2014 in Amazilia. A molecular phylogenetic study published in 2014 found that Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the white-bellied hummingbird was placed by most taxonomic systems in a new genus Elliotomyia.
However, BirdLife International's Handbook of the Birds of the World (HBW) retains it in Amazilia. The white-bellied hummingbird shares genus Elliotomyia with the green-and-white hummingbird (E. viridicauda). The white-bellied hummingbird is 9 to 12 cm (3.5 to 4.7 in) long. Males weigh 4.9 to 6.7 g (0.17 to 0.24 oz) and females 4.5 to 6 g (0.16 to 0.21 oz). Both sexes of both subspecies have a medium length straight bill with a blackish maxilla and a reddish mandible with a dark tip. Adult males of the... Wikipedia →

GBIF citizen-science records
It is estimated from how often the White-bellied Hummingbird is recorded against all the birds logged in Santa Cruz de la Sierra (26 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
