Green-headed Tanager (Tangara seledon) is a bird found in Atlantic forest in south-eastern Brazil, far eastern Paraguay and far north-eastern Argentina. While essentially a bird of humid forests, it is also common in orchards and parks, where it moves through the canopy, making itself inconspicuous, as its apparently flashy blue-green coloration camouflages it well amongst the foliage.
Did you know that ancient Romans called #peridot the “evening emerald,” because its green color did not darken at night, but was still visible by lamplight? Photo: Richard P. Homer. Courtesy: Gems by Design, Inc.
