Orange-bellied euphonia

The orange-bellied euphonia (Euphonia xanthogaster) is a species of bird in the finch family, Fringillidae. They were formerly considered tanagers (Thraupidae). It is found in Bolivia, Brazil, Colombia, Ecuador, Guyana, Panama, Peru, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.

The black-throated euphonia ("Euphonia vittata") is now thought to be a hybrid between the orange-bellied euphonia and the chestnut-bellied euphonia.
