editThe Chocó trogon is about 28 cm (11 in) long and weighs about 104 g (3.7 oz). The male has a yellow bill, a black face and throat, and a white eye. Its crown, back, and breast are green with a bluish tinge, the rump purplish blue, and the belly and vent area red. The upperside of the tail is purplish blue with a broad black tip and the underside is slaty. The folded wing is gray with vermiculation. The female differs in having a slaty maxilla and gray head, back, breast, and upper belly.[4]
