Green-bellied Hummingbird Saucerottia viridigaster Scientific name definitions

The Green-bellied Hummingbird is identified by its brownish lower back and rump and otherwise green upperparts. Its distribution is confined to northeastern Colombia and southwestern Venezuela. The closely related Copper-tailed Hummingbird (Saucerottia cupreicauda) was previously included in the present species; however, it is entirely allopatric, as it is confined to southern Venezuela and northern Brazil.

The Green-bellied Hummingbird's foraging habitats vary from collecting nectar along roadsides to aggressively interacting with other hummingbirds in flowering trees. It inhabits tropical lowland and sub-montane regions around the edges of forests, clearings with trees, light woodlands, second growth, and agricultural areas. There are major changes in its local abundance during different seasons, but the reasons for these fluctuations remains unclear. Its nest and eggs have not been described.
