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.

Among the most common Andean hummingbirds, they are highly aggressive and vocal territory defenders at flower patches.
