Gilded Sapphire

The gilded sapphire (Hylocharis chrysura), also known as the gilded hummingbird, is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found Argentina, Bolivia, Brazil, Paraguay, and Uruguay. == Taxonomy == The names of this species, both English and scientific, have not been settled. The International Ornithological Committee calls it the gilded sapphire (Hylocharis chrysura). The South American Classification Committee of the American Ornithological Society and the Clements taxonomy call it the gilded hummingbird, also with the binomial H. chrysura. BirdLife International's Handbook of the Birds of the World also calls it the gilded hummingbird but with the binomial Amazilia chrysura. The first three systems agree that it shares genus Hylocharis with the rufous-throated sapphire (H. sapphirina). All four agree that it is monotypic. == Description == The gilded sapphire is 8 to 10 cm (3.1 to 3.9 in) long and weighs 4 to 5 g (0.14 to 0.18 oz). Both sexes have a medium length, straight, coral red bill with a black tip. Adult males are mostly iridescent golden-green, with a pale rufous chin and a glittering golden-bronze tail. Adult females are almost the same, but duller overall and with a grayish lower belly.…
