The Magnificent hummingbird (Eugenes fulgens) was originally known as Rivoli's Hummingbird, in honour of the Duke of Rivoli. Males are very dark, with a small white spot behind the eye; the crown is iridescent purple crown, the upperparts dark green, the gorget is glittering green, and the rest of the underparts are blackish. The female lacks the iridescent gorget and crown; the upperparts are green, and the underparts are pale greyish. It flies more slowly than the smaller hummers, sometimes it will even glide. It is also more of an insect gleaner than other hummer species. They occur in mountains from the southwestern United States through Costa Rica and central America to western Panama.
