Slaty-tailed Trogon is a typical trogon of Central America. It feeds on fruit and insects in the canopy of dense humid forest. The species often is detected by its voice, a series of deep croaks. Like other species of trogons, Slaty-tailed often remains on a single perch for long periods, before sallying out to grab fruit or capture an insect. The male Slaty-tailed Trogon has a green head, back, and throat, orange bill, and red underparts with a slate-colored undertail; the female is dull gray throughout except for a red belly. Slaty-tailed Trogon occurs from southern Mexico south through Central America to northwestern South America in humid lowland rainforest.
