Fairly small fork-tailed hummingbird of lowlands. Males have an iridescent green head and breast and a violet belly, but in poor light appears evenly dark overall. Females are green above, light gray below. Note the slightly drooping bill on both sexes. One of the most common hummingbirds in lowland Amazonia; found in a variety of open forested habitats from young rainforest and forest edges to treefall gaps and gardens.
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.
