Andean Emerald

Overview

The Andean Emerald is found along the lower slopes and foothills of the Andes and adjacent lowlands in northern South America, favoring forest edge, clearings, and gardens with flowering plants. Its relatively pale underparts compared to related Amazilia hummingbirds make it a fairly straightforward species to recognize within its range.

Both sexes show an iridescent green throat and back, but the underparts are largely white or very pale, a contrast that helps separate it from other similarly built green hummingbirds sharing its range that show more buffy or gray bellies.

Feather ID Notes

Throat and back feathers show a bright, glossy green iridescence, while the belly and lower underparts are notably pale white to very light gray - cleaner and less buffy than in many related species. The tail shows a blue-tinged, somewhat forked shape.

• Throat feathers: green, glossy
• Back feathers: green, glossy
• Underparts: white to pale gray, unusually clean
• Tail feathers: blue-tinged, moderately forked The combination of a green throat/back with distinctly pale, whitish underparts helps distinguish this species from other Amazilia-type hummingbirds with buffier bellies.

Plumage Details

Sexes are similar in the Andean Emerald, both showing the green throat and back with pale underparts, though females may appear marginally duller. Juveniles show softer, less glossy feather edges. There is no strong seasonal plumage change, with an annual molt maintaining feather condition.

Habitat & Range

This species occupies forest edge, clearings, and gardens at foothill and lower montane elevations along the Andes in northern South America, including Colombia, Ecuador, and parts of Venezuela and Peru. Most populations are resident, with limited local elevational movement.

Behavior & Field Notes

Andean Emeralds feed on nectar from a variety of flowering plants at forest edges and in gardens and also take small insects. They can be territorial around good nectar sources but are generally not as aggressive as some larger hummingbird species. Nests are small, cup-shaped structures built in shrubs or low trees. Calls include soft chips and light twittering notes.
