About Trogon personatus Gould, 1842
The masked trogon (scientific name Trogon personatus Gould, 1842) is a mid-sized trogon species. On average, it measures 27 centimetres (11 inches) long and weighs 56 grams (2.0 ounces). Similar to all other trogons, this species exhibits sexual dimorphism. For male masked trogons, the upperparts, head, and upper chest show varied glossy coloration, ranging from glossy green and reddish-bronze to golden-green, depending on the subspecies. Their belly and lower breast are red, and a narrow white band separates the lower breast from the greenish upper chest. Males have a distinct eye-ring that is red for most subspecies, though it tends to be orange in the subspecies native to the tepuis. Female masked trogons are brown across their upperparts, and have a pinkish to red belly and breast. The white band that divides the brown and red sections on their underside is often either narrow or obscured. All subspecies of female masked trogon have a partial white eye-ring.
