Trogoniformes contains only one family, the Trogonidae. The word "trogon" is Greek for "nibbling" and refers to the fact that these birds gnaw holes in trees to make their nests.
Trogons are typically residents of tropical forests.
They feed on insects and fruit, and their broad bills and weak legs reflect their diet and arboreal habits. Although their flight is fast, they are reluctant to fly any distance. Trogons are generally not migratory, although some species undertake partial local movements.
Trogons have soft, often colourful, feathers with distinctive male and female plumage. They nest in holes dug into trees or termite nests.
The Elegant Trogon and Eared Trogon reach the south of the United States.
