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.
Crypsirina is a small genus of long-tailed passerine birds in the crow and jay family, Corvidae. The two species are highly arboreal and rarely come to the ground to feed. The generic name is derived from the Greek words kruptō, meaning "to conceal," and rhis or rhinos, meaning "nostrils".
The four species of avocets are a genus, Recurvirostra, of waders in the same avian family as the stilts. The genus name comes from Latin recurvus, 'curved backwards' and rostrum, 'bill'. The common name is thought to derive from the Italian (Ferrarese) word avosetta. Francis Willughby in 1678 noted it as the "Avosetta of the Italians".
Pharomachrus is a genus of birds in the family Trogonidae. Pharomachrus is from Ancient Greek pharos, "mantle", and makros, "long", referring to the wing and tail coverts of the resplendent quetzal.
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 anis are the three species of birds in the genus Crotophaga of the cuckoo family. They are essentially tropical New World birds, although the range of two species just reaches the United States.
The golden-headed quetzal or corequenque is a strikingly coloured bird in the genus Pharomachrus. It is found in moist mid-elevation forests from eastern Panama to northern Bolivia.
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.
Guttera is a genus of birds in the family Numididae. Established by Johann Georg Wagler in 1832, it contains four species:
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.
Cyrtonyx is a bird genus in the New World quail family Odontophoridae.
The chestnut-headed tesia is a small insectivorous songbird formerly of the "Old World warbler" family but nowadays placed in the bush warbler family (Cettiidae).
Whitehead's broadbill is a species of bird in the family Calyptomenidae. It is endemic to the mountain ranges of north-central Borneo, where it mainly inhabits montane forests and forest edges at elevations of 900–1,700 m (3,000–5,600 ft). It is 24–27 cm (9.4–10.6 in) long, with males weighing 142–171 g (5.0–6.0 oz) and females weighing 150–163 g (5.3–5.7 oz). Males are vivid green and have a black throat patch, black spots on the ear-coverts and back of the neck, and black markings and streaking all over the body. The tails and flight feathers are also blackish. Females are smaller and lack the black markings on the head and underparts. Juveniles look similar to adults but have fewer black markings.
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 bare-cheeked trogon is a species of bird in the family Trogonidae found in the rainforests of western central Africa.
The bar-tailed trogon is a species of bird in the family Trogonidae. It is a resident bird to central Africa that eats primarily insects and fruit.
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.
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 crested quetzal /ketSAHL/ is a species of bird in the family Trogonidae native to South America, where it is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela. Its natural habitat is subtropical or tropical moist montane forests.
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.
