The Neotropical Trogoninae, containing four genera, Trogon, Priotelus, Pharomachrus and Eupilotis. The two Caribbean species of Priotelus were formerly different ones (Temnotrogon on Hispaniola), and are extremely ancient. The two quetzal genera, Pharomachrus and Eupilotis are possibly derived from the final and most numerous genus of trogons in the Neotropics, Trogon. A 2008 study of the genetics of Trogon suggested the genus originated in Central America and radiated into South America after the formation of the Isthmus of Panama (as part of the Great American Interchange), thus making trogons relatively recent arrivals in South America. Within the genus Trogon, a division of species that coincides with female plumage type is well supported. Females with brown breasts and heads characterize one clade (including T. rufus), whereas females in the other clade (including T. comptus) have gray breasts and heads. Females of T. rufus and T. mexicanus both have brown heads. Male plumage does not appear to be informative at this level; species with red or yellow underparts are interspersed in both clades. 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

Physical charateristics

The male has a yellow bill and reddish eyering, a green head, chest, and upperparts with a white band separating the chest from the red underparts, and a blackish tail. Females are gray above and below save for the red belly. This is a description of the Black-tailed Trogon. Apparently the Ecuadorian Trogon is similar except for its white eyes.
