The Amazilia Hummingbird (Amazilis amazilia) is a species of hummingbird, a family of small near passerine birds. The Loja hummingbird (A. amazilia alticola), with less rufous to the underparts, is sometimes considered a subspecies of the amazilia hummingbird.
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.
The Ruby-throated Hummingbird (Archilochus colubris) is a species of hummingbird that generally spends the winter in Central America, Mexico, and Florida, and migrates to Canada and other parts of Eastern North America for the summer to breed. It is by far the most common hummingbird seen east of the Mississippi River in North America.
