Genus

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 is dark glossy green above and on the chest while the sides of the head and the throat are black. Also a the faint orange-red eye-ring. The white bar across the breast and the red underparts are distinctive as is the pattern on the under-tail which is black with narrow white bars and white tips to the feathers. The female has brown replacing the dark green and the undertail pattern looks greyish with 3 white bands and a narrow subterminal black bar.

Habitat

It is found mainly on the edge of humid forest and in woodland and a variety of other edging habitats.

Reproduction

Nest is a shallow unlined cavity often in rotten trees, 1-5 meter up. Clutch size is 2-3 eggs incubated for about 16 days.

Feeding habits

In contrast to the other Trogon species more insects and less fruit. Mainly beetles, ants, grasshoppers and caterpillars

Conservation

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
The Collared Trogon is distributed from Mexico through Central America to Colombia and the Amazon Basin. There is a disjunct population in eastern Brazil. In Suriname confined to the interior.
Collared Trogon status Least Concern
