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 Oryzoborus angolensis.
The chestnut-bellied seed finch was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his Systema Naturae under the binomial name Loxia angolensis. Linnaeus based his description on "The Black Gros-Beak" that had been described and illustrated in 1764 by the English naturalist George Edwards. Edwards's illustration was from a live bird belonging to the barrister Philip Carteret Webb. Edwards mistakenly believed that the bird had come from Angola. The chestnut-bellied seed finch does not occur there and the type locality is now designated as eastern Brazil.

Rare
Under 5% of wildlife watchers report a Chestnut-bellied Seed-Finch sighting in Itatiaia National Park on a given day, based on 60 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 220th most-seen of the 352 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and November–January
In those months about 10% of wildlife watchers report a Chestnut-bellied Seed-Finch in Itatiaia National Park on a given day, against under 5% in February–April and June–October, the lowest months. Those are among Itatiaia National Park's wettest months, with about 260 mm of rain a month against 25 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Chestnut-bellied Seed-Finch sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 15
Of the 15 parks where we can rate Chestnut-bellied Seed-Finch sightings, Itatiaia National Park ranks 9th at under 5%. The best odds are in Serra dos Órgãos National Park (Brazil, about 20%), Manu National Park (Peru, about 10%) and Iguaçu National Park (Brazil, about 10%).
Same genus: Sporophila
The closest relatives of the Chestnut-bellied Seed-Finch that you can see in Itatiaia National Park (genus Sporophila, Typical Seedeaters and Seed-Finches) are Double-collared Seedeater (about 40%) and Buffy-fronted Seedeater (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chestnut-bellied Seed-Finch is recorded against all the birds logged in Itatiaia National Park (60 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
