Green-bellied Hummingbird

The green-bellied hummingbird (Saucerottia viridigaster) is a species of hummingbird in the "emeralds" tribe Trochilini of subfamily Trochilinae. It is found in Colombia and Venezuela. == Taxonomy and systematics == The green-bellied hummingbird 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 by most taxonomic systems to the resurrected genus Saucerottia. The green-bellied hummingbird previously was assigned six subspecies. By early 2023 most taxonomic systems had created the copper-tailed hummingbird (S. cupreicauda) containing four of them. They retain the other two subspecies in the green-bellied, the nominate S. v. viridigaster (Bourcier, 1843) and S. v. iodura (Reichenbach, 1854). However, the South American Classification Committee of the American Ornithological Society does not recognize the copper-tailed hummingbird as a separate species. == Description == The green-bellied hummingbird is 8 to 10.5 cm (3.1 to 4.1 in) long and weighs 4.5 to 6.7 g (0.16 to 0.24 oz). Both sexes of both subspecies have a straight, medium length, blackish bill with a pink to reddish base to the mandible. Adult males of the nominate subspecies have a dull…
