The Masked Trogon is a mid-sized trogon, averaging 10.5 inches (27 cm) in length and 2 ounces (57 g) in mass. Like all trogons, it is sexually-dimorphic. The male is variously glossy green, reddish-bronze or golden-green above (depending on the subspecies), with a similarly colored chest edged by a narrow white band, and a red lower breast and belly. The female is brown above, with a pinkish to red belly and breast; the white band separating brown and red on her underside is often either narrow or obscured.
Like all trogons, the Masked Trogon feeds on both fruits and insects.
The Masked Trogon excavates a cavity nest in the soft wood of a rotting vertical tree trunk.
