Green-and-black Fruiteater
Pipreola riefferii
The green-and-black fruiteater is 17.5 to 20 cm (6.9 to 7.9 in) long and weighs 46 to 61 g (1.6 to 2.2 oz). The sexes have different plumage. Adult males of the nominate subspecies P. r. riefferii have an entirely blackish green head and upper breast with a yellow band ("collar") around its base except on the nape. Their upperparts and tail are green and the wings mostly that color; the wing's tertials have white tips. Their underparts are yellow with black streaks that are heavier on the flanks than in the center. Females have a green head instead of the male's black and no yellow collar. Voice: The song of most subspecies of the green-and-black fruiteater has variously been written as "tic-tic-ti-ti-ti-tiseeeeeeeeeeeeaa" and "ts-s-s-s-s-s-se-eeeeeeeeuuw". Their call is a "ery high-pitched, sibilant ti-ti-ti-ti for up to 5 seconds, dying away". Subspecies P. r. tallmanorum's call is different, "ti-ti-ti-seeee" with a thin, high-pitched last note.

Orange-breasted Fruiteater
Pipreola jucunda
The male orange-breasted fruiteater has a glossy black head and throat and green upper parts. The breast is bright orange and the belly yellow with green mottling at the side. The female is similar in appearance to the female masked fruiteater with green upper parts and green and yellow streaked underparts. Both sexes have yellow eyes, orange bill and greyish-green legs. This bird grows to a length of about 18 centimetres (7 in). The song is similar to that of the black-chested fruiteater, a high-pitched ascending "pseeeeeweet".
