Зелёный металлохвост Metallura williami

Short-billed hummingbird found near tree line in the high Andes. Male is deep green with a dark and sometimes glittering throat patch; female is similar but lacks throat patch and is scaled buff or rufous below. Tail color varies geographically; it can be green or blue, and it can even show a bit of rufous on top, though never as much as the tail of Tyrian Metaltail. Feeds on small flowers in páramo and at the edge of elfin forest.
