![]() ![]() It is found in Tobago, Trinidad, Venezuela, and possibly Grenada. The copper-rumped hummingbird was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other hummingbirds in the genus Trochilus and coined the binomial name Trochilus tobaci. Gmelin based his description on the "Tobago Humming-Bird" that had been described in 1782 by the English ornithologist John Latham in his A General Synopsis of Birds. The copper-rumped hummingbird was formerly placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that the genus Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the copper-rumped hummingbird was moved by most taxonomic systems to the resurrected genus Saucerottia. However, BirdLife International's Handbook of the Birds of the World (HBW) retains it in Amazilia. ![]() The genus Saucerottia had been introduced in 1850 by the French naturalist Charles Lucien Bonaparte. The genus name is from the specific epithet saucerrottei for the steely-vented hummingbird, the type species. The epithet was coined in 1846 by Adolphe Delattre and Jules Bourcier to honor the French physician and ornithologist Antoine Constant Saucerotte. ![]() These seven subspecies of copper-rumped hummingbird are recognised by world-wide taxonomic systems: The specific epithet tobaci is from the island of Tobago, the type locality. The copper-rumped hummingbird is 9 to 11 cm (3.5 to 4.3 in) long. Both sexes of all subspecies have a straight, medium length, blackish bill with a pinkish base to the mandible. tobaci have bronze-green upperparts with purple-red uppertail coverts. They have dark golden-green underparts with reddish brown undertail coverts. Adult females are similar though their upperparts are a less intense bronze-green and they have some whitish on the chin and upper throat. Juveniles resemble females but have some grayish brown on the throat and belly. monticola is darker than the nominate and has a steel blue to violet-blue tail. aliciae has some copper in its upperparts, a blue-black tail, and cinnamon-rufous undertail coverts.įeliciae 's back is more of a golden-green than the nominate's and its tail is bluish black. Erythronotos has slightly darker underparts than the nominate and some dark purplish in the uppertail coverts. ![]()
