Around 27 cm in size, weighing between 85 and 90 grams. Adult males have a uniform gray head and upper breast and a metallic green mantle, fading to a violet-blue rump. The bill is pale blue-grey, and the eyes are yellow. The uppertail is blue-green with a black tip, and the wings are dark, with outer webs of the primaries white. The dark gray upper breast is separated from the bright yellow belly and undertail, with a creamy white breastband.

Mountain Trogon
Trogon mexicanus
The mountain trogon measures 11.5–12.5 in (29–31.5 cm) in length. It weighs between 61.5 and 85 g (2.2 and 3.0 oz), with a mean of 71 g (2.5 oz). Like all trogons, it is sexually dimorphic. The adult male is green on the crown, nape and upperparts; the upper side of its tail is bluish-green, with black tips to the rectrices. His face and throat are blackish, with an orange-red orbital ring and a bright yellow bill. He is green on the chest and red on the belly and undertail; the two colors are separated by a narrow band of white. Voice: The mountain trogon has several vocalizations. If alarmed, it gives a sharp, low-pitched call variously transcribed as "cut" or "tuck". In flight, it gives a quick, low-pitched call transcribed as "cut-a-cut-cut". When perched, it makes a slow, repetitive "cowh" or a "tucka-tucka-tucka". Young mountain trogons make quiet hissing calls when food begging, and when approached by potential predators.
