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.
Harpactes is a genus of birds in the family Trogonidae found in forests in South and Southeast Asia, extending into southernmost China. They are strongly sexually dimorphic, with females generally being duller than males. Their back is brownish, the tail is partially white, and males of most species have red underparts. They feed on arthropods, small lizards and fruit.
The elegant trogon, previously known as the coppery-tailed trogon, is a near passerine bird in the trogon family native to Central America. The etymology of the word trogon comes from the Greek word trōgein, meaning "to gnaw", which describes how this species prepares its nests in trees.
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 Bornean crested fireback is a medium-sized forest pheasant from Borneo and the Bangka Belitung Islands. It is the type species of the genus Lophura. Prior to 2023, it was referred to as simply the crested fireback as the Malayan crested fireback was lumped with this species, though both have since been split.
The Sumatran trogon is a species of bird in the family Trogonidae. It was formerly considered conspecific with the Javan trogon under the common name blue-tailed trogon.
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 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 Cuban trogon or tocororo is a species of bird in the family Trogonidae. It is endemic to Cuba, where it is also the national bird.
The common name blue-tailed trogon can refer to more than one species of bird in the trogon family:
