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 Santiago on a given day, based on 2,182 verified sightings from GBIF citizen-science data. It is the 21st most-seen of the 110 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a Common Diuca-Finch in Santiago on a given day, against about 20% in March and November–January, the lowest months. That is one of Santiago's wettest months, with about 45 mm of rain against 5 mm in December.
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 2 cities where we can rate Common Diuca-Finch sightings, Santiago has the highest daily chance: about 30%. Next come Mendoza (Argentina, under 5%).
Same family: Thraupidae
The closest relatives of the Common Diuca-Finch that you can see in Santiago (family Thraupidae, Tanagers and Allies) are Grassland Yellow-Finch (about 20%), Mourning Sierra-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 Santiago (2,182 verified sightings), 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.
