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.
The Malabar trogon is a species of bird in the trogon family. It is found in the forests of India and Sri Lanka. In India it is mainly found in the Western Ghats, hill forests of central India and in parts of the Eastern Ghats. They are insectivorous and although not migratory, may move seasonally in response to rain in hill forest regions. Like in other trogons, males and females vary in plumage. The birds utter low guttural calls that can be heard only at close quarters and the birds perch still on a branch under the forest canopy, often facing away from the viewer making them easy to miss despite their colourful plumage.
The Guianan trogon, is a near passerine bird in the trogon and quetzal family Trogonidae. It is found in Brazil, French Guiana, Guyana, Suriname, Trinidad, and Venezuela.
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 from northern Sonora and Chihuahua south to western Michoacán. The species has occurred on rare occasions in southeastern Arizona, where it has been recorded nesting.
Apalharpactes is a genus of birds in the family Trogonidae. They are restricted to humid highland forest on the Indonesian islands of Java and Sumatra. Unlike all other Asian trogons, their plumage is mainly green above and yellow below. Compared to most trogons, the sexual dimorphism is relatively small. The two species in the genus resemble each other, but A. reinwardtii is larger than A. mackloti, and the male A. mackloti has a chestnut rump-patch, which A. reinwardtii lacks. They feed on arthropods, small lizards and fruit.
The Javan trogon is a bird species in the family Trogonidae. It was previously grouped with the Sumatran trogon as a single species, known as the blue-tailed trogon. However, differences in size, weight, and plumage have led to their classification as separate species. Both species were once included in the genus Harpactes alongside other Asian trogons, but due to differences in plumage, they have been reclassified into their own genus, Apalharpactes.
The bare-cheeked trogon is a species of bird in the family Trogonidae found in the rainforests of western central Africa.
The Philippine trogon is a species of bird in the family Trogonidae. It is endemic to the Philippines found on regions of Luzon, East Visayas and Mindanao. It is the only species of trogon in the country. While not a threatened species, its population is declining due to habitat loss and hunting.
Diard's trogon is a species of bird in the family Trogonidae. It is found in Brunei, Indonesia, Malaysia, Singapore, and Thailand. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
The scarlet-rumped trogon is a species of bird in the family Trogonidae. It is found in Brunei, Indonesia, Malaysia, Myanmar, and Thailand. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical swamps, and subtropical or tropical moist montane forest. It is threatened by habitat loss.
The red-headed trogon is a species of bird in the family Trogonidae.
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.
The orange-breasted trogon is a species of bird in the family Trogonidae. It is a colorful, sedentary species that inhabits the lower canopy of the lowlands and forest of southern China, southeast Asia, Borneo, Sumatra and Java.
The cinnamon-rumped trogon is a species of bird in the family Trogonidae or Trogons which are some of the most colourful birds on Earth especially the quetzals found in the Neotropics. There is very little known about this family of birds as a whole and even less information on the cinnamon-rumped trogon.
Ward's trogon is a species of bird in the family Trogonidae. Its range includes the northeastern parts of the Indian subcontinent stretching eastwards to Southeast Asia. It is found in Bhutan, India, Tibet, and Myanmar. It also has a disjunct population in northern Vietnam, but there are no recent records from there. Its natural habitats are temperate forests and 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 pavonine quetzal is a species of bird in the family Trogonidae, the trogons. It is also known at the peacock trogon, red-billed train bearer, or viuda pico rojo in Spanish. The pavonine quetzal lives in the Neotropics, more specifically in the northern region of the Amazon basin, spreading from Colombia to Bolivia. The most notable characteristics helpful in identifying this bird are its plumage, red beak, and its distribution - it is the only quetzal occupying the lowland rainforest east of the Andes.
The orange-bellied trogon is a subspecies of the collared trogon in the family Trogonidae. It is now usually considered as a morph of the collared trogon, but was previously sometimes treated as a separate species. It is found in the Talamancan montane forests of Costa Rica and Panama.
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.
The green-backed trogon, also known as the Amazonian white-tailed trogon, is a bird in the trogon family Trogonidae. It is widely distributed across the Amazon rainforest with a disjunct population on the southeast coast of Brazil. As with all trogons, this species is sexually dimorphic. The male has a yellow belly without a white breastband, a blue head with a pale-blue orbital eye-ring, a blue bill, a green back and a green tail that is mostly white below. The female is duller with a dark grey head, a dark grey back and some black barring beneath the tail.
