Description wikipedia

The Tyrian metaltail (Metallura tyrianthina) is a species of hummingbird in the subfamily Lesbiinae, the brilliants and coquettes. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela. The Tyrian metaltail is 9 to 10 cm (3.5 to 3.9 in) long and weighs 2.7 to 5.1 g (0.10 to 0.18 oz). Both sexes of all subspecies have a short, straight, black bill. The male of the nominate subspecies has bottle green upperparts and gray underparts with pale fringes on the feathers. It has an emerald green throat and a slightly forked glistening bronze tail. The female is also bottle green above. Its throat and upper breast are ochre-orange with olive green spots and the lower breast and belly are whitish with green spots. Its outer tail feathers have whitish tips. The plumage of the Tyrian metaltail's other subspecies differ from those of the nominate in some significant ways. M. t. districta has a violet tail and the female's underparts are not spotted. Both sexes of M. t. chloropogon have a coppery red tail; the male is otherwise almost completely black and the female has only a few spots on the throat and upper breast. M. t. oreopola's tail is golden red. The male's upperpart feathers have coppery bars near the ends and its underparts are green with pale fringes to the feathers. The female's throat and upper breast have few spots. M. t. quitensis has a longer bill than the nominate and a bronze-olive tail. M. t. septentrionalis's tail is purple-blue with green inclusions and the male's underparts are white with bronze-olive spots. M. t. smaragdinicollis has a violet tail like districta but the female's throat and upper breast are heavily spotted like those of the nominate.
