Sparkling Violetear

A large, brilliant hummingbird of the Andes and high Venezuelan tepuis, sparkling violetears display glittering blue-green plumage with an iridescent violet-blue ear patch and chin that sparkle intensely in sunlight — delivering on their evocative name. Found at elevations of 1,200–3,000 meters across Venezuela, Colombia, Ecuador, and Peru in montane forest and scrub. Among the most common Andean hummingbirds, they are highly aggressive and vocal territory defenders at flower patches.
