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.
Exotic species flags differentiate locally introduced species from native species.
Naturalized: Exotic population is self-sustaining, breeding in the wild, persisting for many years, and not maintained through ongoing releases (including vagrants from Naturalized populations). These count in official eBird totals and, where applicable, have been accepted by regional bird records committee(s).
Provisional: Either: 1) member of exotic population that is breeding in the wild, self-propagating, and has persisted for multiple years, but not yet Naturalized; 2) rarity of uncertain provenance, with natural vagrancy or captive provenance both considered plausible. When applicable, eBird generally defers to bird records committees for records formally considered to be of "uncertain provenance". Provisional species count in official eBird totals.
Escapee: Exotic species known or suspected to be escaped or released, including those that have bred but don't yet fulfill the criteria for Provisional. Escapee exotics do not count in official eBird totals.
