The Green-fronted lancebill (Doryfera immaculata) is a hummingbird species found in the mountainous regions of South America, particularly in countries like Venezuela, Colombia, Ecuador, Peru, and Bolivia. It inhabits montane forests near fast-flowing streams at elevations between 1,200 and 2,500 meters. This medium-sized hummingbird is characterized by its distinctive long, straight bill that can reach up to approximately 36.5 mm in length, which it uses to access nectar from tubular flowers. The species exhibits minimal sexual dimorphism, with both males and females displaying predominantly green plumage with a blue-green crown.
