Comments: Open woodland, pine-oak association, scrubby woodland and second growth, primarily in arid or semi-arid situations, less frequently in humid woodland (Tropical to lower Temperate zones) (AOU 1983). Mountain canyons. Costa Rica: hillsides, ravines, gullies, evergreen forest; usually keeps well up in canopy, coming lower to nest or feed (Stiles and Skutch 1989). Nests usually in natural tree cavities or abandoned woodpecker holes, 2-12 m above ground.

Migration
Non-Migrant: Yes. At least some populations of this species do not make significant seasonal migrations. Juvenile dispersal is not considered a migration.
Locally Migrant: Yes. At least some populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.
Found year-round throughout most of range. Northernmost populations are partially migratory (AOU 1983).

Trophic Strategy
Comments: Feeds on insects (e.g., grasshoppers, mantids, bugs, beetles, moths) and some fruit (e.g. grapes, cherries) (Terres 1980). Gleans insects from leaves and twigs while hovering in mid-air. Sallies to snatch berries, arillate seeds, and insects from foliage (Stiles and Skutch 1989).

Elegant Trogon
The Elegant Trogon (Trogon elegans) (formerly the "Coppery-tailed" Trogon), is a near passerine bird in the trogon family.[2] It breeds from southeasternmost Arizona in the United States to northwestern Costa Rica. It occasionally is found as a vagrant in southeasternmost and western Texas.
It is a resident of the lower levels of semi-arid open woodlands and forests. It nests 2–6 metres (7–20 ft) high in an unlined shallow cavity, usually selecting an old woodpecker hole, with a typical clutch of 2–3 eggs.
Trogons have distinctive male and female plumages, with soft, often colourful, feathers. This species is 28–30 centimetres (11–12 in) long and weighs 65–67 grams (2.3–2.4 oz). Both sexes have a white undertail with fine horizontal black barring. The undertail also has large white tips spaced evenly ending in a black terminal band. Both have a yellow bill, orange-red undertail coverts and lower belly, and a white horizontal breast stripe.
The male Elegant Trogon has a metallic deep green head, upper breast and back, black face and throat, and red-orange lower breast and belly. He shows grey upperwing coverts. The female has a metallic bronze head, upper breast, back, upper tail and upperwing coverts. She shows a dull white upper belly, and a small white vertical stripe behind the eye.
The usual call is a croaking "co-ah co-ah co-ah". The trogon will also include some chattering notes.
Elegant Trogons feed on insects and fruit, often taken in flight. Their broad bills and weak legs reflect their diet and arboreal habits. Although their flight is fast, they are reluctant to fly any distance. They typically perch upright and motionless.
Subspecies
T. elegans has five recognized subspecies, including the nominate subspecies:[2]
- Trogon elegans ambiguus Gould, 1835
- Trogon elegans canescens Van Rossem, 1934
- Trogon elegans elegans Gould, 1834
- Trogon elegans goldmani Nelson, 1898
- Trogon elegans lubricus J. L. Peters, 1945
