The trogons (family Trogonidae) are a family of birds belonging to the monotypic order Trogoniformes distributed across tropical regions across the globe. These birds are strictly arboreal and generally inactive, sitting still on branches in the canopy for long periods. This behavior makes it often difficult to spot them, despite the bright-colored plumage of all members of the family. They are monogamous, breed in tree holes and defend their territories, so they are often best detected by their voice.

The family comprises 47 species in 7 genera. Genus Apaloderma (3 species) includes mostly green birds endemic to Afrotropical forests. Genera Apalharpactes (2 species) and Harpactes (10 species) are all distributed along the Indomalayan realm, the first genus including mostly yellow and the last red birds. However, the largest diversity of the genus takes place in the New World. Genera Euptilotis (1 species) and Pharomachrus (5 species) are known as quetzals and sport shiny green and red plumages, as the Antillean endemic genus Priotelus (2 species). Genus Trogon (24 species) includes an array of mostly blue and yellow birds distributed all across the Neotropics.
