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 →

Possible
About 20% of wildlife watchers report a White-bellied Hummingbird sighting in Amboró National Park on a given day, based on 94 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 69th most-seen of the 273 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July and September
In those months about 30% of wildlife watchers report a White-bellied Hummingbird in Amboró National Park on a given day, against about 10% in February, April–May, August and October–December, the lowest months. Those are among Amboró National Park's driest months, with about 100 mm of rain a month against 340 mm in January. June has too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most White-bellied Hummingbird sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate White-bellied Hummingbird sightings, Amboró National Park has the highest daily chance: about 20%. Next come Manu National Park (Peru, under 5%).
Same family: Trochilidae
The closest relatives of the White-bellied Hummingbird that you can see in Amboró National Park (family Trochilidae, Hummingbirds) are Fork-tailed Woodnymph (about 30%), Planalto Hermit (about 20%) and Golden-tailed Sapphire (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-bellied Hummingbird is recorded against all the birds logged in Amboró National Park (94 verified sightings from 2019 to 2026), 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.
