Green-bellied hummingbird
The green-bellied hummingbird ("Saucerottia viridigaster"), also known as the Tepui hummingbird, is a species of hummingbird in the family Trochilidae. It is found in Brazil, Colombia, Guyana, and Venezuela. Taxonomy. The western taxa of the Andean slopes and the eastern taxa of the Tepui region are sometimes considered separate species, with the former retaining the scientific and common name, while the latter is named the copper-tailed hummingbird ("Saucerottia cupreicauda", with races "duidae" and "laireti"). As the variation largely is clinal, most authorities, notably SACC, consider it a single species. This species was formerly placed in  the genus "Amazilia". A molecular phylogenetic study published in 2014 found that the genus "Amazilia" was polyphyletic. In the revised classification to create monophyletic genera, the green-bellied hummingbird was moved to the resurrected genus "Saucerottia". Distribution and habitat. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and heavily degraded former forest.
