The diuca finch (Diuca diuca) is a species of bird in the tanager family Thraupidae. It is the only member of the genus Diuca. It is found in Argentina, Bolivia, Brazil, Chile, and Uruguay. Its natural habitats are subtropical or tropical dry shrubland, subtropical or tropical high-altitude shrubland, and heavily degraded former forest.
The diuca finch was formally described in 1782 by the Chilean naturalist Juan Ignacio Molina under the binomial name Fringilla diuca. The specific epithet is from the Araucano names Diuca or Siuca for this species. With the transfer of the glacier finch (formerly white-winged diuca finch) to Idiopsar or Chionodacryon, the diuca finch is now the only member of the genus Diuca, which was introduced in 1850 by the German naturalist Ludwig Reichenbach.

Possible
About 30% of wildlife watchers report a Common Diuca-Finch sighting in Nahuel Huapi National Park on a given day, based on 338 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 23rd most-seen of the 111 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
April, September–October and December
In those months about 40% of wildlife watchers report a Common Diuca-Finch in Nahuel Huapi National Park on a given day, against about 10% in June and July, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common Diuca-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.
Yes
Of the 3 parks where we can rate Common Diuca-Finch sightings, Nahuel Huapi National Park has the highest daily chance: about 30%. Next come Península Valdés (Argentina, about 30%) and Torres del Paine National Park (Chile, under 5%).
Same family: Thraupidae
The closest relatives of the Common Diuca-Finch that you can see in Nahuel Huapi National Park (family Thraupidae, Tanagers and Allies) are Patagonian Sierra-Finch (about 40%), Grassland Yellow-Finch (about 10%) and Grey-hooded Sierra-Finch (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Diuca-Finch is recorded against all the birds logged in Nahuel Huapi National Park (338 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.
