Rivoli's hummingbird (Eugenes fulgens) is a large hummingbird. It was usually considered the only member of the genus Eugenes and is also called the magnificent hummingbird. Many taxonomic authorities, such as the International Ornithological Committee, split the northern nominate subspecies E. f. fulgens from the larger southern race of Costa Rica and Panama, E. f. spectabilis, into distinct species,[2] in which case the nominate fulgens is renamed Rivoli's hummingbird and spectabilis is named the Talamanca hummingbird or admirable hummingbird.
Rivoli's hummingbird breeds in mountains from the southwestern United States to Honduras and Nicaragua. It inhabits the edges and clearings of montane oak forests from about 2,000 m altitude up to the timberline, though bird feeders often attract them to lower altitudes. During the breeding season they live around ravines in mountain areas of southern Arizona and New Mexico. They feed in open meadows where flowers are abundant.
