Mountain Trogon

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. The underside of his tail is black with three large white blocks created by white tips to the outer rectrices. His primaries are blackish, with black and white vermiculations on the wing coverts. The female is warm brown on her head and upperparts; her tail is rufous-brown on the upperside, with black tips to the rectrices. She has a small white crescent in front of her eye and a bold white crescent behind her eye. Her bill is dark above. Her chest is warm brown, separated from her brown lower chest and red belly by a narrow band of white. Her undertail is black and white; the outer webs of the rectrices are barred black and white, while the inner webs are black, broadly tipped with white. Her primaries are blackish with white outer webs, which form white streaks along her folded wing. Her wing coverts are pale brown, with dusky vermiculations.
