The sparkling violetear (Colibri coruscans) is a species of hummingbird widespread in highlands of northern and western South America, including a large part of the Andes (from Argentina and northwards), the Venezuelan Coastal Range, and the Tepuis.

C. c. germanus is found on the tepuis of southern Venezuela, western Guyana, and the adjacent Brazilian state of Roraima.

The species inhabits a variety of open landscapes including the edges of subtropical and temperate forest, woodland, gardens, city parks, and páramo.

[8][9] According to one study, the sparkling violetear has the smallest mean blood-air barrier thickness (0.183 μm) and the highest mass-specific respiratory surface area (87 cm2/g) in birds.

[6] The sparkling violetear forages for nectar from a wide variety of flowering plants at all levels of the forest from the ground to the canopy.

[6] The sparkling violetear's breeding seasons vary across its range, from July through October in Venezuela to December through February in Argentina.

It also sings "a medley of chips, squeals, gurgling sounds and short warbles" during aerial display.
