Trogoniformes is not on the 2020 Official Bird List.
The order Trogoniformes contains the trogons and quetzals. Its name comes from the Greek "trogon", meaning nibbling, referring to the fact that these birds gnaw holes in trees to make their nests. Their diet consists mainly of insects and fruit, and have broad bills and weak legs. Most of these birds live in tropical or subtropical forests. They are territorial and monogamous, are cavity nesters (nests are dug into rotting wood), and lay two to four white/pastel colored eggs. The male elegant trogon has a metallic green head, upper breast, and back, a reddish belly, and a black face. The females are mostly bronze with a dull white belly, and have a small vertical white stripe behind the eye.
