Violaceous trogon has been split into the following species:
The trogons and quetzals are birds in the order Trogoniformes which contains only one family, the Trogonidae. The family Trogonidae contains 46 species in seven genera. The fossil record of the trogons dates back 49 million years to the Early Eocene. They might constitute a member of the basal radiation of the order Coraciiformes and order Passeriformes or be closely related to mousebirds and owls. The word trogon is Greek for "nibbling" and refers to the fact that these birds gnaw holes in trees to make their nests.
Quetzals are strikingly colored birds in the trogon family. They are found in forests, especially in humid highlands, with the five species from the genus Pharomachrus being exclusively Neotropical, while a single species, the eared quetzal, Euptilotis neoxenus, is found in Mexico and very locally in the southernmost United States. Quetzals are fairly large, slightly bigger than other trogon species. The resplendent quetzal is the national bird of Guatemala because of its vibrant colour.
The collared trogon is a near passerine bird in the trogon family, Trogonidae.
The Guianan trogon, is a near passerine bird in the trogon family, Trogonidae. It is found in humid forests in the Amazon basin of South America and on the island of Trinidad. Until recently, this species, the gartered trogon of Mexico, Central America, and northern South America, and the Amazonian trogon of the western Amazon were all considered to be conspecific and collectively called violaceous trogon.
The Dlinza Forest is a subtropical forest or Coastal Scarp Forest in Eshowe, Zululand, South Africa, one of five natural forests running in a 100 km line running northwest from the coast. Others are the Ongoye, Entumeni, Nkandla and Qudeni Forests. They are the most important forests in southern Africa from the aspect of unique biodiversity. It contains rare birds, chameleons, snails, butterflies, moths, frogs and beetles. Dlinza is the home of more than 65 species of birds, including the endangered spotted ground thrush which breeds here, rare Delegorgue's pigeon, magnificent purple-crested turaco and Narina trogon.
The white-tailed trogon is a near passerine bird in the trogon family. It is found in tropical humid forests of the Chocó, ranging from Panama, through western Colombia, to western Ecuador. It was formerly considered a subspecies of T. viridis, which is widespread in South America east of the Andes, but under the English name white-tailed trogon.
The elegant trogon is a near passerine bird in the trogon family. Along with the eared quetzal, it is the most poleward-occurring species of trogon in the world, ranging from Guatemala in the south as far north as the upper Gila River in Arizona and New Mexico. The most northerly populations of subspecies ambiguus are partially migratory, and the species is occasionally found as a vagrant in southeasternmost and western Texas.
Trogon is a genus of Coraciimorphae birds in the trogon family. Its members occur in forests and woodlands of the Americas, ranging from southeastern Arizona to northern Argentina.
The Narina trogon is a largely green and red, medium-sized, bird of the family Trogonidae. It is native to forests and woodlands of the Afrotropics. Though it is the most widespread and catholic in habitat choice of the three Apaloderma species, their numbers are locally depleted due to deforestation. Some populations are sedentary while others undertake regular movements. The species name commemorates Narina, mistress of French ornithologist François Levaillant, whose name he derived from a Khoikhoi word for "flower", as her given name was difficult to pronounce.
The eared quetzal, also known as the eared trogon, is a near passerine bird in the trogon family, Trogonidae. It is native to streamside pine-oak forests and canyons in the Sierra Madre Occidental of Mexico south to western Michoacán and southeasternmost Arizona in the United States. This range includes part of the Madrean Sky Islands region of southeastern Arizona, southwestern New Mexico, and northern Sonora.
The Javan trogon is a species of bird in the family Trogonidae. The species was once lumped together with the Sumatran trogon in a single species, the blue-tailed trogon, but differences in size, weight and plumage have led to the two being split. These two species were once themselves lumped with the rest of the Asian trogons in the genus Harpactes, but have been split into their own genus due to differences in plumage.
The red-naped trogon is a species of bird in the family Trogonidae. It is found in Brunei, Indonesia, Malaysia, and Thailand. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Whitehead's trogon is a species of bird in the family Trogonidae. It is endemic to the island of Borneo, where it is an uncommon resident in primary mountain forest. One of Borneo's largest trogons at 29 to 33 cm long, it is sexually dimorphic. The male is crimson on the head, nape, and underparts, with a black throat and grey chest; the rest of his upperparts are cinnamon-coloured. The female is similarly patterned, but cinnamon-brown where the male is scarlet. The species was first described for science by Richard Bowdler Sharpe in 1888, who named it for British explorer and collector John Whitehead. There are no subspecies.
The blue-crowned trogon is a species of bird in the family Trogonidae. It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Paraguay, and Peru. Its natural habitats are subtropical or tropical moist lowland forests and heavily degraded former forest.
The black-headed trogon is a species of bird in the family Trogonidae. It is found in Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, and heavily degraded former forest.
The mountain trogon, also known as the Mexican trogon, is a species of bird in the family Trogonidae. First described by William John Swainson in 1827, it is resident in Guatemala, Honduras, and Mexico and has occurred in El Salvador as a vagrant. Like all trogons, the mountain trogon is sexually dimorphic. The male is metallic green on the crown, nape, upperparts and chest, the latter separated from its bright red belly and vent by a narrow band of white. The female is warm brown on the head, upperparts and chest, separated from its paler brown lower chest and red belly and vent by a narrow white band.
The Surucua trogon is a species of bird in the family Trogonidae. It is found in humid forest and nearby habitats in south-eastern Brazil, eastern Paraguay, and far north-eastern Argentina and Uruguay. It includes two subspecies; the southern nominate subspecies with a red belly and the northern aurantius with an orange-yellow belly. The latter has sometimes been considered a separate species, the Brazilian trogon. The name orange-bellied trogon has also been suggested, but this leads to confusion with the Central American Trogon aurantiiventris.
The common name blue-tailed trogon can refer to more than one species of bird in the trogon family:
The green-backed trogon, also known as the Amazonian white-tailed trogon, is a near passerine bird in the trogon family.
Melanocephalus is an epithet often used as the second word of a binomial name. It derives from Greek words meaning 'black-headed'. It is used in the names of the following species:
