Métallure de Thérèse Metallura theresiae

Distinctively colored hummingbird restricted to treeline forest and scrub in the Andes of northern and central Peru. No other small hummingbird in its range has coppery plumage; also note the green throat (indistinct on female), short bill, and white spot behind the eye. Tail is faintly greenish underneath and bluish on top. Perches atop bushes when not feeding, and quickly chases away other intruding hummingbirds while giving rapid, high-pitched squeaks.
