==Description== The masked trogon is a mid-sized trogon, averaging {{cvt|27|cm|in}} in length and {{cvt|56|g|oz}} in mass. Like all trogons, it displays sexual dimorphism. The upperparts, head, and upper chest of the male are variously glossy green, reddish-bronze, or golden-green (depending on the subspecies). The belly and lower breast are red; the latter separated from the greenish upper chest by a narrow white band. The male has a distinct eye-ring, which is red in most subspecies, but tending towards orange in the subspecies from the tepuis. 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.<ref name=Hilty>{{cite book |last=Hilty |first=Steven L. |title=Birds of Venezuela |publisher=Christopher Helm |location=London |year=2003 |isbn=0-7136-6418-5 |pages=439–440}}</ref> Females of all subspecies have a partial white eye-ring.<ref name=Hilty/>
