The carbonated sierra finch (Rhopospina carbonaria), also known as the carbon sierra-finch, is a species of bird in the family Thraupidae, the tanagers and allies. It is endemic to Argentina. The carbonated sierra finch has a complicated taxonomic history that is not yet fully resolved. It was formally described in 1837 with the binomial Emberiza carbonaria. It was later assigned to the genus Phrygilus and later still to genus Porphyrospiza. Those genera were long in family Emberizidae which at the time held many New and Old World species. There they were grouped with the cardinalines which were later separated as the family Cardinalidae. A study published in 2007 showed that Porphyrospiza belonged in its present tanager family Thraupidae. Beginning in 2019 most taxonomic systems began reassigning the carbonated sierra finch to the resurrected genus Rhopospina that had been erected in 1851. However, in 2016 BirdLife International's Handbook of the Birds of the World moved it from Phrygilus to Corydospiza and as of late 2025 retains it there.
The carbonated sierra finch is monotypic. The carbonated sierra finch is 14 to 14.5 cm (5.5 to... Wikipedia →

With luck
About 10% of wildlife watchers report a Carbonated Sierra-Finch sighting in Península Valdés on a given day, based on 43 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 54th most-seen of the 96 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Carbonated Sierra-Finch in Península Valdés on a given day, against under 5% in March and April, the lowest months. June and July have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Carbonated Sierra-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.
Only Península Valdés, in our data
Península Valdés is the only park on Wallace's Line with enough records to rate Carbonated Sierra-Finch sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Thraupidae
The closest relatives of the Carbonated Sierra-Finch that you can see in Península Valdés (family Thraupidae, Tanagers and Allies) are Mourning Sierra-Finch (about 70%), Common Diuca-Finch (about 30%) and Grassland Yellow-Finch (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Carbonated Sierra-Finch is recorded against all the birds logged in Península Valdés (43 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.
