The amazilia hummingbird occurs in western Peru and south-western Ecuador. It is generally common, and can regularly be seen even in major cities such as Lima and Guayaquil. It prefers dry, open or semi-open habitats, but also occurs in forest. In its range it is easily recognized by the combination of a black-tipped red bill and mainly rufous underparts. It is a territorial species.[2]

Its diet consists of small insects and nectar of flowering Erythrina, Psittacanthus, and other flower corollas of medium length.[3] It can spend roughly 80% of its time resting, using the rest of its time to forage, hunt, and defend its territory (often against Coereba flaveola).[2] It breeds year round with cup like nests only ~3cm above the ground.[3]

The amazilia hummingbird was formerly placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that the genus Amazilia was polyphyletic.[4] In the revised classification to create monophyletic genera, the amazilia hummingbird was moved to the resurrected genus Amazilis that had been introduced in 1855 by George Gray.[5][6]

Some ornithologists have proposed that the subspecies Amazilis amazilia alticola, the Loja hummingbird, should be treated as a separate species.[7][8]
