Slaty-tailed Trogon
Trogon massena
Trogons have distinctive male and female plumages, with soft, often colorful, feathers. The slaty-tailed trogon is 30 to 35.5 cm (12 to 14 in) long and weighs about 140 to 155 g (4.9 to 5.5 oz). The nominate male has an orange-red bill and a dull black face, chin, and upper throat with a red to orange ring around the eye. The upperparts are metallic green that tends to golden green on the back and bluish green on the crown and rump. The breast is metallic green and the belly and vent deep red. The folded wing has fine black and white vermiculation that looks gray at a distance. Voice: The slaty-tailed trogon's song is "a steady deliberate series of cow or cue notes"; another description is "a deep full-throated wuk, wuk, wuk …." Its calls include "a quiet clucking huh-huh-huh-huh" and a "chuckling chatter".
