The chestnut-breasted chlorophonia (Chlorophonia pyrrhophrys) is a species of bird in the family Fringillidae, the finches and euphonias. It is found in Colombia, Ecuador, Peru, and Venezuela. The chestnut-breasted chlorophonia is a chunky, short-tailed, stubby-billed bird. It is about 12 cm (4.7 in) long and weighs 16 to 18 g (0.56 to 0.63 oz). The species is sexually dimorphic. Adult males have a green forehead and a rich cyanine-blue crown and nape. They have a thin dark red band between them that extends past the eye and a thin pale blue band at the base of the nape. Their lores, face, throat, and upper breast are shiny emerald-green with a thin black line beneath the upper breast. Their mantle, back, and upperwing coverts are bright green and their rump bright yellow. Their tail's central feathers are dusky with thin green edges and the rest dusky with wide green edges. Their primary coverts and most flight feathers are blackish with bright green edges; their tertials are green. The center of their lower breast, belly, and vent are deep chestnut with bright yellow on either side. Adult females are duller and plainer than males. They have a turquoise-blue crown and nape. The rest of their face and upper breast are generally patterned like the male's but a paler green and lack the black line below the upper breast and the pale blue band below the nape. Their back and rump are a slightly darker green than their upper breast and their upperwing coverts dusky with wide green edges. Their tail is like the male's. Most of their flight feathers are blackish with dark green edges and their tertials are green. Their lower breast and the rest of their underparts are dull yellowish. Both sexes have a dark brown iris, a blackish bill with a pale gray base to the mandible, and dark gray legs and feet. Immatures are mostly green with a yellowish belly.
