They have large eyes, stout hooked bills, short wings, and long, squared-off, strongly graduated tails; black and white tail-feather markings form distinctive patterns on the underside. Males have richly colored metallic plumage, metallic on the upperparts.[1] Although many have brightly coloured bare eye-rings, they lack the colorful patches of bare facial skin in their African counterparts, Apaloderma.[2] Females and young are duller and sometimes hard to identify in the field.[1] Eggs are white or bluish-white, unlike the pale blue eggs of quetzals.[2] See the family account for further details.

Taxonomy

The genus Trogon was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the green-backed trogon (Trogon viridis) as the type species.[3][4] The name of the genus is from the Ancient Greek τρωγων trōgōn for "fruit-eating" or "gnawing".[5] The name had previously been used by the German naturalist Paul Möhring in 1752 for the blue-crowned trogon (Trogon curucui).[6]
