The chestnut-bellied seed finch (Sporophila angolensis ) is a species of bird in the family Thraupidae, but was until recently placed in Emberizidae.
It is found widely in shrubby and grassy areas in tropical and subtropical South America. It has been replaced west of the Andes (and in Central America) by the closely related thick-billed seed finch (S. funerea ). The two have often been considered conspecific as the lesser seed-finch, using the older scientific name O. angolensis.
