Golden-bellied starfrontlet
The golden-bellied starfrontlet is a species of hummingbird in the "brilliants", tribe Heliantheini in subfamily Lesbiinae. It is endemic to Colombia.
Taxonomy and systematics
The golden-bellied starfrontlet and most other members of genus Coeligena were at one time placed in genus Helianthea but have been in their current placement since the mid-1900s.The International Ornithological Committee, the Clements taxonomy, and BirdLife International's Handbook of the Birds of the World recognize the golden-bellied starfrontlet as a monotypic species separate from the Perija starfrontlet and golden-tailed starfrontlet. The South American Classification Committee of the American Ornithological Society treats those three as subspecies of the golden-bellied starfrontlet sensu lato but is seeking proposals to elevate all three to species status.
The golden-bellied starfrontlet's specific epithet commemorates Charles Lucien Bonaparte.
