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.

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.

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 chestnut-hooded laughingthrush is a species of bird in the laughingthrush family Leiothrichidae endemic to Borneo. Described by the British ornithologist Richard Bowdler Sharpe as a distinct species in 1879, it was subsequently considered a subspecies of the chestnut-capped laughingthrush until 2007, when it was again raised to species status by the ornithologists Nigel Collar and Craig Robson. It is 22–24 cm (8.7–9.4 in) long, with a chestnut brown head and chin, with grey feathering on the top of the head. The upperparts and the side of the neck are slaty-grey, with a long white wing patch. The throat, breast, and upper belly are dull yellowish-brown, with purer grey flanks and a reddish-brown vent, lower belly, and thighs. It has a yellow half eye-ring behind and below the eye, while the tail has a blackish tip. Both sexes look similar, while juveniles are duller than adults.
